PULSE OPTICAL BARRIER ON LIGHT BEAMS OF VISIBLE BAND

摘要

A pulse optical barrier on light beams of visible band comprises a transmitting unit and receiving one. The transmitting unit as emitter comprises powerful light-emitting diode matrix and collecting lens for formation of needed spatial aperture angle of light pulses of visible band, and the receiving unit with photoreceivers arranged in space restricted by aperture angle comprises a signal amplitude gate and synchro integrator with synchro detector to provide resistance to interference of extraneous light sources.
