DEVICE FOR CONTROL OF THE LASER GUIDANCE Russian patent published in 2018 - IPC G01M11/02 G01C3/08 

FIELD: instrument engineering.

SUBSTANCE: invention relates to the optical instrumentation and can be used to control the parameters of a laser instrument containing a radiating and observational channels. Device for control of laser guidance device contains two channels, one of which is a sighting or televisual, and the second laser, the objective, the test object located in the focal plane of the lens, made in the form of a grid applied to a transparent plane-parallel plate and representing transparent areas, namely strokes, containing on an opaque background at least one circular transparent element-diaphragm, as well as dashed transparent elements in the form of an incomplete crosshair, symmetrical to the center of the diaphragm, a mirror system is located between the objective and the test object, behind which, in turn, is the system of illumination of the test object, and the receiver of radiant energy. Optical block is made in the form of a rhombus-prism and two wedges located in front of the objective, and before the optical unit there is a protective glass, the optical unit is made in the form of a fixed prism turning the optical axis by 90° and consisting of a glued rhombus prism and prisms AP-90°, and prism AP-90° installed in front of the objective, on its optical axis and is interfaced with the laser channel, combining the last with the optical axis of the objective, and up to the rhombus-prism in the sight channel there are two wedges with the possibility of rotation around the optical axis of the sighting channel and with the possibility of fixation in the chosen position. Diaphragm, located in the center of the test object, is made in the form of a circular transparent element, the system of illumination of the test object is made in the form of a matrix from radiation sources, and between the illumination system and the test object a frosted plate with a transparent central zone is installed, the outer radius of the matted zone, illuminated by the matrix of light sources, exceeds the radial coordinates of the points of all transparent elements of the test object, the system of mirrors is made in the form of mirror elements forming a rigid mirror module, in addition, behind the illumination system an optical node in the form of a second rhombus prism is located, on the optical axis of which the radiation receiver behind the second protective glass is located.

EFFECT: possibility of installing the device on a mobile object.
