Abstract

The invention relates to an external field of view splicing device based on a cooling infrared system. It includes a time-sharing exposure control unit and a reflector group and a detector arranged on the path of the incident light of the optical system; the reflector group includes a fixed reflector and a porous rotating reflector; the reflector group also includes a The motor for the rotating movement of the reflector; the porous rotating reflector is arranged on the reflection optical axis of the fixed reflector; the porous rotating reflector is circular; Fan-shaped mirrors of the same size. The invention provides an external field of view splicing device which reduces the number of detectors and saves production costs.

Description

technical field [0001] The invention belongs to the technical field of shooting range photoelectric measurement, relates to realizing the measurement of multiple targets within a large field of view coverage, and in particular to an external field of view splicing device based on a cooling infrared system. Background technique [0002] In the field of photoelectric shooting range measurement and control, with the development of measurement technology, the requirements for imaging systems are getting higher and higher. When measuring the target, due to the fast speed, large number of measured targets, and the large field of view covered, the size of the image sensor is limited by the processing technology and cannot be made very large, and the operating distance requirements of the system must be taken into account. Therefore, the application of a single high-speed camera cannot capture a complete picture and provide more details. It is necessary to use field of view stitchin...
