CA 2352349
A detection system is disclosed comprising one or more transmitters (10, 11) of electromagnetic radiation and one or more co-operating receivers (12, 13), characterised in that at least one optical element (14, 15, 16, 17) is provided which utilises total internal reflection to redirect the path of radiation such that the transmitter is not directly in line with the receiver.
L'invention porte sur un système de détection comprenant un ou plusieurs émetteurs (10, 11) de rayonnement électromagnétique et un ou plusieurs récepteurs (12, 13) coopérants. Ce système se caractérise en ce qu'au moins un élément (14, 15, 16, 17) optique utilise la réflexion interne totale pour rediriger la trajectoire de rayonnement de sorte que l'émetteur ne soit pas directement aligné sur le récepteur.
