Optical imaging splicing device of double CCD image splicing detector

Abstract

The invention discloses an optical imaging splicing device of a double CCD image splicing detector which comprises a casing, an object lens group, a composite prism, two uniform CCDs and an optical wedge adjusting mechanism with two double optical wedge components; the double optical wedge components consist of fixed optical wedges and movable optical wedges; the optical wedge adjusting mechanism is arranged in front of one CCD target surface; and optical wedge angle directions of the two double optical wedge components are mutually perpendicular. In installing and debugging process, two adjusting loop-coils connected with the two movable optical wedges by screw threads are rotated, so as to realize precise alignment of splicing edge pixel of semi target optical imaging focusing on two CCD target surfaces. The device of the invention effectively resolves difficulties of debugging operation in prior optical imaging splicing technique. The device has outstanding advantages of simple structure, light weight, convenient and time-saving debugging and high reliability.

Description

technical field [0001] The invention relates to a CCD detector used in a photoelectric reconnaissance and photoelectric tracking system, in particular to an optical imaging splicing device for a double CCD image splicing detector. Background technique [0002] The photoelectric reconnaissance and tracking system has the advantages of strong target detection ability, high tracking measurement accuracy, strong anti-electromagnetic interference ability, strong concealment, and good confidentiality. It occupies an important position in the weapon system used in modern warfare. [0003] CCD detectors have volume, weight and cost advantages, so they become one of the sensors commonly used in most optoelectronic systems. As a necessary part of the photoelectric reconnaissance detection system, CCD detectors are usually used to track targets and monitor the working status of other tracking systems. It generally consists of a CCD (charge-coupled device) and an optical system. Diffe...
