With second eyepiece that described second micro-display links to each other, the display surface of described second micro-display is as the object plane of described second eyepiece;
With second spectroscope that described second eyepiece links to each other, the optical axis of described second spectroscope and described second eyepiece has angle, enters human eye through the described second spectroscope light reflected, and the virtual image of the corona that human eye is seen and described corona are positioned at same orientation.
Because the image display device of two human eye correspondences is identical, below in conjunction with Fig. 2, be example with the image display device of a human eye correspondence wherein, the transmission course of light path is described.
This image display device comprises first micro-display 17, first eyepiece 18 and first spectroscope 19, show image on the display surface of first micro-display 17 through the corona of ccd image sensor 16 transmission, the image of the corona on first micro-display, 17 display surfaces is by first eyepiece 18, form the virtual image of amplifying, after 19 reflections of first spectroscope, enter human eye afterwards, at this moment, human eye just can be seen the virtual image of corona at the corona discharge place.
Described spectroscope is also referred to as semi-transparent semi-reflecting lens, can reflect through the light that eyepiece was handled and enter human eye, so that human eye is seen the virtual image of corona at the corona discharge place, the virtual image that is about to the corona after this Helmet Mounted Display is handled overlaps with the background of the generation corona discharge of reality, to reach the purpose of seeing the virtual image of corona in actual electrical corona place, with the accuracy rate that guarantees to survey.And, because spectroscopical use, when making human eye can see the corona virtual image, also do not influence and normally look thing, the maintainer can wear this Helmet Mounted Display at any time and carry out service work, thereby can find corona phenomenon timely and overhaul timely, avoid the loss of electric system greatly.
Wherein, described day blind ultraviolet imaging enhancer comprises:
The ultraviolet detector 13 that links to each other with described ultraviolet object lens, described ultraviolet object lens 11 images on the test surface of described ultraviolet detector 13, that is to say, and the test surface of described ultraviolet detector 13 is the test surface of described day blind ultraviolet imaging enhancer;
What obtain at the test surface of ultraviolet detector 13 is the real image of corona, at this moment, intensity through the light signal of the corona of ultraviolet detector 13 is still very weak, human eye is difficult to observe, therefore, output face at ultraviolet detector 13 connects a gleam image intensifier 14, amplifies with the intensity to the light signal of corona, so that follow-up observation.
Need to prove, do not limit the size of the angle of spectroscope and eyepiece optical axis in two image display devices in the present embodiment, as long as can make through the spectroscope light reflected and can enter human eye, concrete angle can be adjusted according to the concrete ornaments position of each parts in the helmet-mounted display system, preferably, the optical axis of described first spectroscope and described first eyepiece is 30 ° of-60 ° of angles, and/or the optical axis of described second spectroscope and described second eyepiece is 30 ° of-60 ° of angles, preferred, the optical axis of described first spectroscope and described first eyepiece is 45 ° of angles, and/or the optical axis of described second spectroscope and described second eyepiece is 45 ° of angles.
Because the light intensity of described corona discharge is very little, even the light intensity of the corona after gleam image intensifier 14 strengthens also can not be higher than very much the normal light intensity of solar radiation on daytime, therefore, preferably, first spectroscope described in the present embodiment and/or described second spectroscopical reflectivity are greater than transmissivity.Certainly, can be according to the actual detection needs, suitable adjustment first spectroscope and second spectroscopical reflectivity are with the control material object that observes of human eye and the brightness ratio of the virtual image.
And, in the present embodiment for the ease of detection to corona, and after detecting corona discharge, can in time keep in repair, preferably, the object distance of ultraviolet object lens described in the present embodiment is the 0.3m-infinite distance, and the image distance of described first eyepiece and/or described second eyepiece is the 0.3m-infinite distance, and is preferred, the object distance of described ultraviolet object lens is the 0.5m-infinite distance, and the image distance of described first eyepiece and/or described second eyepiece is the 0.5m-infinite distance.
In sum, the Helmet Mounted Display that the embodiment of the invention provided, utilized " day is blind " characteristic of ultraviolet light, adopt the light signal of ultraviolet object lens picked-up corona, filter out the light signal of other wave band except that day blind ultraviolet band by ultraviolet filter, adopt day blind ultraviolet imaging enhancer that the light signal of the corona that absorbs is carried out the spectrum conversion afterwards and strengthen, be converted into the stronger visible light signal of light intensity, make human eye can observe corona phenomenon, adopt the corona signal after optical fiber cone will strengthen to be coupled in the ccd image sensor, by ccd image sensor the image of corona signal is transferred to first corresponding with people's the eyes respectively micro-display and second micro-display afterwards, and respectively by first eyepiece and second eyepiece, form the virtual image of amplifying, light is entered two eyes of people by first spectroscope and the reflection of second spectroscope respectively afterwards, at this moment, human eye just can be seen the virtual image of corona at the corona discharge place.
Because the main day blind ultraviolet band that adopts carries out the detection of corona, be subjected to extraneous light to influence very little, therefore human eye can be seen the virtual image of corona clearly, improved the detection accuracy rate of corona, and because the ultraviolet Helmet Mounted Display itself is easy to carry, only needing that it is worn on head upward gets final product, thereby both hands have been liberated, and, because spectroscopical use does not also influence when making the wearer can see the corona virtual image and normally looks thing, the maintainer can wear this Helmet Mounted Display at any time and carry out service work, thereby can find corona phenomenon timely and overhaul timely, avoid the loss of electric system greatly.
And, owing to adopt a day blind ultraviolet band to carry out the detection of corona in the present embodiment, therefore, still can operate as normal under the weather condition in daylight, greasy weather, accurately the location is applicable to that fully the fault routine of high-voltage transforming system and transmission line of electricity etc. detects.
What describe in detail in the embodiment of the invention only is the light path part of this Helmet Mounted Display, it will be appreciated by those skilled in the art that, be interconnective between above-mentioned each optical element by certain physical construction, and, except that light path part, this Helmet Mounted Display also should comprise power circuit, is used to each element power supply of described Helmet Mounted Display;
