Abstract[English]
An obstruction detection system, including first cube-corner prisms along a first edge of a rectangular detection area, second cube-corner prisms along a second edge of the detection area opposite the first edge, whereby the prisms each include an aperture facing the detection area, and are arranged to create a light channel back and forth across the detection area whereby a light beam projected towards the aperture of one of the first prisms is successively reflected by the first and second prisms back and forth across the detection area, through the light channel at locations along the first and second edges, an emitter emitting light beams towards one of the first prisms, a photodiode measuring intensity of a light beam emitted by the emitter, after it has completely passed through the light channel, and a processor determining a level of obstruction of the light beam based on photodiode output.[French]
L'invention concerne un système de détection d'obstruction, comprenant des premiers prismes à coins de cube le long d'un premier bord d'une zone de détection rectangulaire, des seconds prismes à coins de cube le long d'un second bord de la zone de détection opposé au premier bord, les prismes comprenant chacun une ouverture faisant face à la zone de détection, et étant disposés de manière à créer un canal lumineux traversant la zone de détection de part en part, de sorte qu'un faisceau lumineux projeté vers l'ouverture de l'un des premiers prismes est successivement réfléchi par les premiers et seconds prismes traversant la zone de détection de part en part, à travers le canal lumineux à des endroits situés le long des premier et second bords, un émetteur émettant des faisceaux lumineux vers l'un des premiers prismes, une photodiode mesurant l'intensité d'un faisceau lumineux émis par l'émetteur, après qu'il a complètement traversé le canal lumineux, et un processeur déterminant un degré d'obstruction du faisceau lumineux sur la base d'une sortie de photodiode.
