Abstract
A sort of common path and integrated machine design on TV camera with dual field of view and laser ranging reception was designed. According to the application requirements, the work on device selection about CMOS and avalanche tube was carried out at first. Then, the work on optical, mechanical, and electrical design was carried out. By means of the shared previous objective lens group, the spectroscope coated beam-splitting film and relay lens group were used to achieve the design of common path optical system. The big field of TV camera view was used for searching targets, the small field of TV camera view was used for tracking targets, and the unit of laser ranging reception was used for receiving laser echo. The body tube and the complete machine shell were designed integrally and processed by monoblock casting way, and the whole structural strength of integrated machine was improved. The startup chip for dual H-bridge motor was designed parallelly to improve the operating rated current, and according to the detection results of limit switch, the precise limit control of transmission components by electrical machinery was achieved. Analysis of the design results shows that the image quality of the big/small field of view of integrated machine is good, the image plane is stable, and the unit of laser ranging reception maintains a good working state.
