Optical sensor for verifying object i.e. cylindrical test bar, in monitoring region, has receiver, where angular misalignment between transmitter and receiver is selected such that shadow impact of object on monitoring surface is verifiable

摘要

The optical sensor (10) has a receiver (40) with multiple receiving units, where the size and position of the receiving units are selected in such a manner that an image of a standard object (58) i.e. cylindrical test bar, on the receiver overlaps the receiving units. A transmitter (20) i.e. pulsed light source, is provided, where an angular misalignment between the transmitter and the receiver is selected in such a manner that a shadow impact (52) of the standard object on a monitoring surface (32) is verifiable. An independent claim is also included for a method for verifying an object in a monitoring region.
