FIELD: instrumentation.
SUBSTANCE: claimed device comprises point emitter, photoreceiver system optically communicated with said emitter and including the optical filter, objective lens and photoreceiver mounted in the image objective plane and composed of matrix photoreceiver connected with processing unit. Besides, it comprises the emitter control unit with emitter control channel and microprocessor with outputs connected with emitter control channel input. Microcontroller input is connected with processing unit. Emitter control channel output is connected with emitter input. Note here that this device incorporates two retroreflectors to be mounted at controlled object. Besides, point emitter is located at the objective optical axis within the limits of photoreceiver system so that its emission indicatrix is directed from photoreceiver system to retroreflectors.
EFFECT: electric power saving, simplified servicing and operation.
