OPTOELECTRONIC COORDINATE DETERMINATION SYSTEM Russian patent published in 2022 - IPC G01S3/78 

FIELD: optoelectronic instrumentation.

SUBSTANCE: invention relates to optoelectronic instrumentation and can be used in systems for searching, detecting and determining the coordinates of objects emitting in the ultraviolet (UV) range of the spectrum. To achieve the effect, the system comprises a fairing located along the rays, a receiving lens, the first spectral filter installed in the rear section of the receiving lens, a radiation receiver made in the form of an image intensifier tube, a projection lens, a CCD matrix, to the output of which an information processing unit is connected. The receiving lens is made in the form of sequentially arranged first and second components, in the space between which an additionally introduced second spectral filter is installed. In this case, the first component is made in the form of the first negative convex-concave and the second flat-concave lenses arranged in series. The second component contains the first biconvex lens installed in series, the first surface of which is aligned with the aperture diaphragm, the second biconcave, the third positive concave-convex, the fourth biconvex and the fifth convex-flat lenses.

EFFECT: increasing the detectability of the system and the accuracy of determining coordinates due to the uniform illumination of the spectral filter.
