GCU-OSD10 is designed for search and visualisation the place of portable systems of secret observation (SOS - Secret Observation System), camouflaged in the various items, clothing, working or disconnected compact cameras under different lighting conditions at distances up to maximum 750 m. (depending on weather condition).
Basic operation principle is "cat's eye" effect (light-reflecting effect) lying in ability of optical objects to reflect probing radiation in opposite direction with angle close to its incidence angle. Semi-conducting laser IR diode (transmitting channel) serves as the source of probing radiation. The reflected signal is registered by sensitive video camera on the basis of interleave transfer sensor (reception channel). The Device is developed on non-parallax optical scheme, i.e. with optical alignment of reception and transmitting channels.
Transmitting channel generates laser beam in the form of vertically located rectangular raster. Ability of illuminating raster can be changed if necessary, depending on distance to surveillance object, for reception of the best image contrast. Image focusing on sharpness is carried out by adjustment of video camera objective.
Visualization of surveillance objects is carried out through built in pseudo-binocular. In order to receive better images the body of the Device is equipped with fastening and connection for external 5"LCD-monitor (delivered on request of the Customer), and also with external CCIR standard video signal socket for connection with external monitor, video recorder or computer (with video capture card).
