Abstract:
1. A wide angle sensor system comprising: a) an opto-transmitter for transmitting a beam of light; b) an opto-receiver having an aperture angle of at least 80° and which is disposed at an observation angle of at most 1° with respect to said opto-transmitter, said opto-receiver for receiving a reflection of said beam of light sent by said opto-transmitter; and c) a reflector for reflecting said beam of light sent by said opto-transmitter, said reflector with a multiplicity of cube corners, each cube corner comprising: wherein a cube corner axis of each of the multiplicity of cube corners deviates by up to 15° from an axis normal to a reflector surface in a direction toward said at least one of said cube corner part surfaces having said larger surface area, so that said opto-receiver receives across a substantially 80° angle, a reflected beam having a reflective value greater than 3000 mcd/lx.
