Problems solved by technology

Usually, the dual optical path optical axis debugging method we adopt can ensure that the imaging position error of each optical path on the CCD target surface is about 0.5-1 pixel, which cannot meet the quality requirements of the CCD image output when the dual optical path image is synthesized.

Abstract

The invention discloses a TV camera device with four spliced double-light-path CCDs (Charge Coupled Devices) and belongs to the technical field of photoelectrical imaging. Two same imaging lens sets are adopted by the TV camera device; a turning reflector and an image synthesized compound prism are used for superposing two paths of light energies, so that the light energy on each CCD target surface is doubled; the problem of insufficient light energy on the CCD target surface during the process of splicing four single-light-path CCDs is solved; besides, the image synthesized compound prism, two light-splitting compound prisms and two reflectors are utilized to realize the separation of four CCD mounting surfaces; and a tuning mechanism containing two pairs of double optical wedges is used for eliminating the image position deviation of a two-path optical system, so that the problem of image seamless butt-joint during the process of splicing the four CCDs is effectively solved. The TV camera device provided by the invention has the advantages of simple structure, light weight, low cost, convenience in debugging, high reliability, and the like.

Description

technical field [0001] The invention belongs to the field of photoelectric detection, and relates to a TV camera device spliced ​​with multiple CCD devices, which is mainly used in the photoelectric tracking system of artillery. Background technique [0002] As a necessary part of artillery photoelectric reconnaissance detection system, CCD camera is usually used to track and monitor targets. It generally consists of a CCD imaging device and different optical systems. Different optical systems have different field of view sizes and resolutions. index. For an optical system, when the field of view is large, the resolution is low. In order to expand the field of view without reducing the resolution, it can be realized by receiving optical images of the same field of view optical path by double CCD or multi-CCD splicing. [0003] For the double CCD splicing method with the same optical path, the incident light is usually divided into two paths by using a semi-transparent and s...
