EQUIPMENT FOR DETECTING THE UNIQUENESS OF A PERSON IN A VOLUME

摘要

The invention relates to an equipment for detecting the uniqueness of a person in a given volume in order to check that only one person at a time passes through a hatch for the optical recognition of a person outline, wherein said equipment comprises: an image visualisation device (2), lighting means (4) and a protection glass (5); characterised in that it comprises an absorption high-pass filter (7) provided on the trajectory of the optical axis (X-X); a dichroic filter (6) essentially perpendicular to the optical axis (X-X) of said visualisation device (2) and provided between the visualisation device (2) and the protection glass (5), said dichroic filter (6) being capable of displacement together with the visualisation device (2) relative to the protection glass (5), whereby the reflection generated by the LEDs on the protection glass (5) is selectively and angularly filtered.
