Abstract

The invention relates to a laser TV infrared three-band optical system with a scanning function, including a common aperture telescopic system, a laser telescopic system, a fast scanning mirror, a zoom mirror, a laser beam splitter, a fast scanning mirror, an infrared beam splitter Mirror, TV beam splitter and so on. The common-aperture telescopic system and the laser telescopic system are switched to work with a large field of view through the movement of the zoom mirror and the laser beam splitter. The laser beam, the TV beam and the infrared beam share the fast scanning mirror, and the micro adjustment of the TV optical axis, the laser optical axis and the infrared optical axis is realized by using the two-dimensional movement in the normal direction of the fast scanning mirror. The magnification of the laser telescopic system and the common-aperture telescopic system are consistent, realizing the optical secondary stabilization and visual axis retrace function, and adapting to staring imaging under high-frequency vibration or fast movement of the external turntable.

Description

technical field [0001] The invention belongs to the field of optical design, and relates to a laser TV infrared three-band optical system with a scanning function, in particular to a multi-spectral integrated system, which is used for micro-adjustment of the laser TV infrared three-band optical axis, and can realize optical secondary stability and visual Axis retrace function, suitable for staring imaging under high-frequency vibration or fast movement of the external turntable. Background technique [0002] Modern photoelectric sighting and sighting equipment usually includes thermal imaging cameras, TV cameras, and laser photodetectors, which are widely used in military strikes, fire control, and reconnaissance and early warning. Improving multispectral integration and product stability and accuracy are two important development trend. [0003] In terms of spectral integration, an article published in the journal index Proc.of SPIE Vol.6940 69400S-1 titled Third Generatio...
