Ccd Structure And Layout Of The Car Long Weeks, As The Optical Observation Device

This article addresses comparisons among three configurations, in which CCD cameras are added on the head, behind the relay mechanical or behind the Pechan prism of a kind of type Tank Commander' s Panoramic electro-optical Sight. Finally, a reasonable configuration is selected.According to the focal length by means of imaging principle of camera and knowledge of optical telescopic system to determine values such as focal length and numerical aperture of each configuration, in order to evaluate the effect of the size of the volume on the whole system; Have analysed comparisons are made among three configurations on the implementation, technical difficulties and cost increase as a result of the parts manufacturing difficulties; Have compared the functions that three configurations on theimplementation...
