Day and night telephoto sighting system relates to a video surveillance system that can be used for day and night in common by moving or fixedly installed in a place where boundary work is required.

In particular, many types of devices have been invented in order to expand and apply the area where the security work is limitedly reduced at night when there is no light in the operation of the security system, among which the inventors of the similarly registered invention, the registered patent number 0130306 In the case of the night vision telescope, as in the example shown in Fig. 2, the infrared rays emitted from the infrared launcher are directed toward the direction to be observed, which emits infrared rays outside the observation area. The problem is that the consumption is high and the infrared reach is reduced.

In addition, in performing efficient military boundary work, if the enemy has an infrared detector, a problem that the position of the infrared ray is larger, the faster the position of the enemy can be exposed.

 Patent application 10-2002-0056123 In the case of the infrared light by the optical device, the manufacturing cost is increased due to the peripheral configuration such as the prism and the reconstructed prism reflector when using the refraction and reflection of the light using the prism, and also the weight and volume are increased. The problem arises when used as a portable.

The day and night telephoto sight corrects the infrared rays generated by the infrared ray generating apparatus 50 and the zoom lens 12 and the digital camera 30 between the objective lens 13 and the digital camera 30 as shown in FIG. A telephoto sight composed of a barrel 10 including a lens 11 is configured to emit infrared rays through the objective light 13 and the zoom light 12 axis through the zoom lens 12, thereby adjusting the observation area. The infrared rays passing through the zoom lens 12 and the objective lens 13 emit infrared light only in the observation area, so that the infrared light can be emitted to a long distance even with a small output infrared light, and thus the distance to be observed at night becomes long.

In addition, in the daytime and nighttime use, there is a problem in the structure that normally switches from daytime to nighttime using a port sensor or in this case it does not actively respond to the change in brightness of the area to be observed in the present invention The infrared ray generator 50 is operated in response to the brightness of the observation area by comparing the average brightness pixel of each screen with the set value.

Particularly, when it is mounted on a personal device, it is required to be lightweight and small, so as shown in FIG. In addition, it is possible to aim by zooming in on actual targets, providing the conditions for checking and responding to objects over long distances, especially at night when there is no light.

The configuration of the day and night telephoto collimator is composed of a telescope 10 including a zoom lens 12 and a correcting lens 11 between the objective lens 13 and the digital camera 30 as shown in FIGS. 1 and 3. In the controller, the infrared rays generated by the infrared ray generating device 50 are infrared rays at the refraction angle of the concave lens in order to emit infrared rays to the viewing area along the axis of the emission light 1 passing through the zoom lens 12 and the objective lens 13. The infrared rays are emitted by condensing through the refraction, and the emitted infrared rays pass through the concave lens such that the incident light 2 on the optical axis passing through the objective lens 13 and the zoom lens 12 is transmitted to the digital camera 30. (10) the correction lens (11) mounted inside to correct the focal length by the refraction of the concave lens, and the incident light (2) input from the correction lens (11) is converted into an image signal to the adjusting device (20) Digital camera 30 and the digital car to output Amplifies and converts the video signal input from the D30 and outputs it to the monitor 70, and also stores the input video signal in the storage circuit, and also calculates the difference in brightness between the previously stored video signal and the currently input video signal pixel. If the value is equal to or greater than the set value, the image input signal is stored again. If the value is smaller than the set value, the operation signal of the infrared ray generating apparatus 50 is output, and the position shift signal is output by the operation switch of the zoom lens 12. And a control unit 20, a monitor 70 that receives an image signal of an observation area from the control device 20, and displays an image of the observation area, and the control device 20 and the infrared ray generating device 50. Power supply for supplying all direct current power to the present invention, and one or more infrared LEDs (51) mounted on the outer wall of the digital camera 30 mounted inside the barrel (10) and the adjustment device ( To the output signal of It consists of an infrared ray generating device 50 for generating infrared rays, and the incident and firing of the linear barrel 10 forming a straight line from the objective lens 13 to the digital camera 30 emits infrared rays from one optical axis It is composed of a device for receiving and displaying the reflected wave.

As described above, the function and configuration of the day and night telephoto sight will be described below in detail with reference to the example of the accompanying drawings for each politics.

The correction lens 11 emits infrared rays to the observation area with the emission light 1 axis passing through the zoom lens 12 and the objective lens 13 through the infrared rays generated by the infrared ray generator 50 as shown in the example shown in FIG. 3. When the infrared lens is fired while the zoom lens 12 and the objective lens 13 are adjusted to the viewing area, the focus is limited to the viewing area. Infrared rays are emitted.

In addition, the reflected wave reflected from the object in the observation region by the emitted infrared rays is concave so that the incident light 2 incident on the optical axis via the objective lens 13 and the zoom lens 12 is transmitted to the digital camera 30. It consists of the correction lens 11 is composed of a concave lens for correcting the focal length at the angle of refraction of the lens mounted inside the barrel (10).

As in the example shown in FIG. 3, the digital camera 30 converts the incident light 2 input from the correcting lens 11 into an image signal and outputs the image signal to the adjusting device 20.

In the case of the example shown in FIG. 3, the position at which the digital camera 30 is mounted is composed of a straight barrel 10, which leads to the objective lens 13, the zoom lens 12, and the correction lens 11. It is located at the rear end of the linear incident optical axis.

In the example of the digital camera 30 shown in FIG. 4, the reflected wave reflected and refracted by the half reflector 17 positioned between the zoom lens 12 and the infrared ray generator 50 is transmitted to the digital camera 30. The mounting position is determined by the reflection angle of the half reflector 17.

The half reflecting mirror 17 is a half reflecting mirror used in an optical microscope, and the incident light 2 incident on the optical axis via the objective lens 13 and the zoom lens 12 as shown in FIG. The inclined surface is formed to be transmitted to the inside of the articulated barrel 10.

The adjusting device 20 includes an amplifier circuit, an oscillator circuit, a storage circuit, a signal conversion circuit, an operation circuit, and an input / output circuit to perform the following functions.

The adjusting device 20 amplifies and converts the video signal input from the digital camera 30 and outputs the video signal to the monitor 70.

In addition, the input image signal is stored in a storage circuit.

In addition, the arithmetic circuit compares the pixel brightness difference between the previously stored video signal and the currently input video signal and inputs it into the storage circuit to store the pixel brightness value of the current video input signal again when it is higher than a preset value. When the brightness value of the image input signal and the previously stored image signal are compared, the operation signal of the infrared ray generating apparatus 50 is output when the brightness value is less than the set value.

In addition, when adjusting the viewing distance and area by the user's operation, the input circuit outputs the position shift signal by the operation switch of the zoom lens 12.

Depending on the shape of the short zoom lens 12, only the position adjusting input switch may be mounted on the adjusting device 20.

The mounting position of the adjusting device 20 is mounted on the barrel 10 as in the example shown in FIG. 5 according to the use of the present invention, or is detached from the barrel 10 to monitor the monitor 70 While observing with), it is divided into a detachable type to be mounted at a position where the zoom lens 12 embedded in the barrel 10 installed in the viewing area can be manipulated.

The monitor 70 receives an image of the observation area according to a user's selection and receives an image signal of the control device 20 to display an image of the observation area on the screen.

The mounting position of the monitor 70 is configured as the example shown in Figure 5 according to the use of the present invention divided into a mounting type mounted on the barrel 10 and a separate type as described in the adjusting device (20) do.

The power supply device is a device for supplying a full DC power supply to the present invention, and in the case of a portable device, a rechargeable battery or a battery is used, and the fixed type device includes a device for supplying direct current including a circuit for converting AC into direct current.

Infrared generator 50 is composed of one or more infrared LEDs 51 with concave lenses on the outer wall of the digital camera 30 mounted inside the barrel 10 as shown in the example shown on the right side of FIG. LED 51 type infrared ray generator for mounting infrared rays to the zoom lens 12 by the angle of refraction of the correction lens 11 to generate infrared rays by the output signal of the adjusting device 20 ( 50).

The application example of the LED 51 type infrared ray generating device 50 is composed of a straight tube 10 which forms a straight line from the objective lens 13 to the digital camera 30, so that the incident and the emission are performed at one optical axis. It is used in a straight barrel 10 for emitting infrared rays and receiving reflected waves.

In the case of observing an object of a long distance or a long distance at night when there is no light, the LED 51 type infrared ray generator 50 is impossible to observe due to the limit of the amount of infrared rays generated by the LED 51 type infrared ray generator 50. In order to overcome this, as shown in FIG. 4, one or more infrared lamps 55 are mounted inside the barrel 10 to generate infrared rays by the output signal of the adjusting device 20. It is divided into a (55) type infrared ray generator 50.

In the case of the lamp 55 type infrared ray generator 50, a high amount of infrared rays is required, so that the infrared rays generated by the lamp 55 type infrared ray generator 50 are digitally reflected by the infrared rays reflected from the correction lens 11. As a means for compensating for this, the camera 30 may not be used above the amount of infrared rays generated when the image signal is detected to be disturbed. 55) the infrared ray generating apparatus 50 is used a lot.

The configuration of the refracting tube 10 is a high output infrared ray generated by the infrared ray generator 50 to observe the long-distance or long-distance objects at night without light, the infrared ray generator 50 and the zoom lens 12 IR is emitted to the observation area with the semi-reflector 17 positioned between the and the emission light 1 axis passing through the zoom lens 12 and the objective lens 13, and the infrared rays reflected from the observation object by the emitted infrared rays. Semi-reflective mirror 17 mounted inside the barrel 10 by forming an inclined surface such that the reflected light is incident on the optical axis passing through the objective lens 13 and the zoom lens to the digital camera 30. Reflected wave refracted by the () is composed of a refractive tube 10 that is displayed through the digital camera 30 and the monitor 70.

To date, the auxiliary equipment for performing night boundary work has been used to emit high-power infrared light in a large area 84 directed to an area to observe infrared light as shown in the example shown in FIG.

Therefore, in the case of the day and night telephoto collimator, infrared rays are emitted only to the region 83 adjusted to the region to be observed as in the example shown in FIG. 2, so that the distance that can be observed even with a small amount of infrared rays becomes long. Will be.

In addition, when the distance to be observed is limited, there is an effect of minimizing energy consumption by giving an amount of infrared rays generated.

In particular, if the enemy uses an infrared camera or an infrared verification device that is used for military purposes, and the enemy possesses an infrared camera or an infrared verification device, the infrared angle is widened. In the case of the invention, the infrared light is emitted only in the area where observation is required, so even in a long distance or a long distance, the infrared emission angle is limited to the observation area, thereby reducing the probability of exposure to the enemy.
