Abstract

Control system for motorised optics with variable focal length. The present invention refers to a system for control of motorised optics with variable focal length 3 based on an electronics card 2 which can be connected to one of the expansion slots of a computer 1 for the purpose of controlling the positioning of the focal length and the corresponding focus. The card developed 2 consists of a control stage 2.1 which allows adjustment of the selected focal length and the corresponding focus of optics for a video camera, by means of the actuation of the respective motors 2.3 which the optics feature. Feedback in the control loop 2.4 allows precise adjustment and supplies information to the user on the position taken up. The system communicates with a computer via an interface 2.2 giving an automatic or else operator-guided mode of operation. It can be used in security or monitoring applications, quality control, remote operation of robot systems and teleconferencing.
