AUTOMOTIVE OPTICAL SENSOR Russian patent published in 2014 - IPC G08G1/16 G01S17/93 

FIELD: physics, optics.

SUBSTANCE: invention relates to optoelectronic devices to be used at carries as extra detector of objects in areas invisible for driver. Proposed optical sensor comprises transceiving channels, each including electronic unit, pulse source of optical radiation and photoreceiver, all being connected with electronic unit. Said electronic unit comprises reflected signal processor to execute control algorithm on the basis of measurement of time interval between radiation and registration of signal reflected from the object. Optical radiation source and photoreceiver are arranged, preferably, nearby so that their optical axes are parallel. The number of radiators in said sensor is defined by the relationship n ≥ β/α, where n is the number of radiators, β is central angle of controlled sector, α is beam angle.

EFFECT: higher precision and reliability of detection.
