FIELD: instrumentation engineering. SUBSTANCE: laser system has hinge-connected frequency-pulsed laser and photoreceiving device with parallel optical axes. Hinge connection provides for their oscillatory-rotary motion at an angular velocity determined by given formula. Hinge is secured in center of platform rotating about vertical axis at angular velocity determined by divergence of radiation of frequency-pulsed laser in horizontal plane and pulse radiation frequency of frequency-pulsed laser. Threshold device of laser radiation intensity, counter of frequency-pulsed laser radiation pulses, pickup of angular position of photoreceiver and frequency-pulsed laser, coordinate determination unit, and signalling device are connected in series to photoreceiver output. Photoreceiver lens is provided with narrow-band interference filter. EFFECT: enhanced detection of optoelectronic objects. 1 dwga |
