Coaxial photoelectric reconnaissance system

Abstract

The invention, which belongs to the field of reconnaissance systems, particularly relates to a coaxial photoelectric reconnaissance system comprising a Cassegrain non-focus coaxial two-inverse commonoptical path, an infrared imaging system and a visible light imaging system. The Cassegrain non-focus coaxial two-inverse common optical path includes a primary mirror and a secondary mirror; and light emitted by a target is reflected and collimated by the primary mirror and the secondary mirror twice and then parallel light is emitted. A reflection mirror is arranged at the path of parallel lightemission by the Cassegrain non-focus coaxial two-inverse common optical path to realize light turning of parallel light. A first transmission-reflection mirror is arranged at the reflection light path of the reflection mirror to realize reflection of infrared light and transmission of visible light. The visible light imaging system is used for receiving visible light transmitted by the first transmission-reflection mirror and carrying out imaging; and the infrared imaging system is used for receiving infrared light reflected by the first transmission-reflection mirror and carrying out imaging. Therefore, visible-light and infrared-band optical systems and a laser optical system are integrated under the condition of small size, so that target observation in various environments is realized.

technical field [0001] The invention belongs to the field of reconnaissance systems, and in particular relates to a coaxial photoelectric reconnaissance system. Background technique [0002] At present, individual reconnaissance technologies such as long-distance thermal imaging technology, CMOS image sensing technology, and semiconductor laser pumping technology are gradually becoming mature, and integrating multiple sensing technologies to complement each other's advantages can effectively complete day and night battlefield surveillance. , target recognition and instruction, guided fire strikes and other tasks. In China, visible light and infrared band optical systems and laser optical systems are usually designed separately and independently, resulting in a large system size and weight. At the same time, the optical axis non-parallelism between each system requires more complicated calibration and is not stable in the later stage. In addition, when the external observati...

Problems solved by technology

In China, visible light and infrared optical systems and laser optical systems are usually designed separately and independently, resulting in a large system size and weight. At the same time, the optical axis non-parallelism between the systems requires more complicated calibration and is not stable in the later stage.

In addition, when the external observation environment changes, such as the target is blocked, camouflaged, and smoky, ...
