Abstract:
Aiming at the increasing demands for the search scope and oprerating distance of current military photoelectric searching and tracking sighting device TV camera system, through analysis and comparison of the mature TV camera system, a research direction using the structure with miniaturized fixed focal length, multifield of view (FOV) was clearly determined. Based on the research direction, a design idea using embedded modular front lens group optomechanical srtucture was proposed, which can realize the fixedfocal length, multiFOV TV camera system miniaturization design plan. After optical design and optomechanical integration design, a 4FOV TV camera with large optical zoom range(20), stable optical axis and 4 FOVs sharing 2 common imaging devices was finally completed, it can meet the needs of existing military searching and tracking photoelectric sighting device TV camera system.
