SURVEILLANCE DEVICE-SIGHTS WITH BUILT-IN LASER RANGE FINDER Russian patent published in 2019 - IPC F41G3/06 G02B23/08 G02B23/12 

FIELD: optics.

SUBSTANCE: invention relates to the field of optoelectronic equipment and can be used in the fire control system of armored vehicles. Surveillance device-sights with built-in laser range finder comprises head part and vertically arranged optical and optoelectronic channels. Optical channel includes a lens, a collective, a two-component wrapping system, a rectangular prism, a plane-parallel plate, an eyepiece and a matching optical system with a photodetector of a range finder. Optoelectronic channel has a head mirror, a thermal imaging lens, a thermal imaging photodetector, a microdisplay and an eyepiece. Between plane-parallel plate and eyepiece movable and fixed sighting grids are installed. In order to change the magnification, the first and second components of the erecting system are made to move in two extreme positions along the optical axis.

EFFECT: enabling simplification of optical channels, night surveillance without active illumination, high quality of the optical image, as well as possibility of arrangement of the photodetector of the range finder in the optical system of the day channel.
