Abstract
Optical detector capable of operating in proximity mode or in proximity with background elimination mode, including an emission system and a reception system having hardware and software detection and configuration means capable of recognizing the appropriate mode by measuring the distance of the background, comparing a reception signal with at least one threshold, and automatically switching the reception system into proximity mode or proximity with background elimination mode depending on the result of the comparison.
