Abstract:

In an infrared communications link, a transmitter is connected to a plurality of infrared light emitting diodes disposed about an arcuate surface to illuminate a generally rectangular area with pulsed optical energy. When a receiver having a plurality of photodiodes is disposed within the generally rectangular area the information contained in the pulsed optical energy is recovered. The combination of the transmitter and receiver provide a transceiver that is ideally suited for providing two way communication between a fixed station and an automatically guided vehicle in an electromagnetically hostile environment such as a highly automated factory.
