MULT-CHANNEL OPTOELECTRONIC DEVICE OF SHIP AIR DEFENSE SYSTEM FOR DETECTION AND TRACKING OF AIR AND SURFACE TARGETS (VERSIONS) Russian patent published in 2010 - IPC F41G7/26 

FIELD: weapons and ammunition.

SUBSTANCE: group of inventions relates to devices of ship air defense system with optoelectronic information means (OEIM) for detection and tracking of air and surface targets. OEIM in the form of television camera, thermal imager and laser range finder. OEIM are installed in tight vessel with protective optical windows (POW). According to the first version of invention, POW are arranged with their wedging alignment in direction that minimises angular parallax between OEIM within the limits of specified range of distances to target, and autocollimating images from tight vessel POW are used as test ones for online monitoring of angular position of photo-optical axes, threshold sensitivity and angular resolution of OEIM. In the second version tight vessel of POW is arranged with drives that are independent on the main gimbal suspension, and dynamically moving autocollimating images from POW of tight vessel are used as test ones to control parametres of driving circuit of targets tracking. Device is equipped with monolithic glass angled reflector and glass wedge, which are in optical contact and have various index of refraction. Wedge is arranged with angle, value of which provides for preservation of angular direction of passing light beam. Internal surface of tight vessel imitates photometric Ulbricht sphere, and inner surface of tight vessel cover is Lambert reflector.

EFFECT: increased distance of targets detection and increased accuracy of their coordinates measurement.
