21 LASER LIGHT TRANSMITTER AND PROXIMITY DETECTOR ABSTRACT A laser light transmitter includes a laser light emitting diode (1, 2) situated at a focal point of a specially shaped lens (3, 4) which produces a very thin intense fan-shaped beam. A proximity detector employs one or two such laser light transmitters (infrared) in order to radiate a fan-shaped beam which is intercepted by a person or object thereby scattering laser light, by diffuse reflection. A cylindrical lens (5) receives a reflected component and this is detected by sensors (6) which are connected to circuitry including a synchronous detector (12) and comparator network (13, 14). The synchronous detector (12) is driven by a square wave oscillator (8) which modulates the laser light.
