Abstract
An underwater wireless optical communication, UWOC, unit () for underwater deployment on a submerged earth layer () or structure (). The UWOC unit is configured for wireless optical communication in an underwater environment, and comprises an optical transmitter (), an anidolic optical receiver (), and a processor (). The optical transmitter is configured to transmit data by emitting an optical signal () into the surroundings. The optical receiver includes an optical detector (), which is omnidirectionally sensitive and configured to receive further optical signals approaching substantially along an azimuthal plane orthogonal to a nominal axis (A) through the UWOC unit. The processor is coupled to the optical receiver, and configured to process received further optical signals. The unit may be configured to determine an inter-unit distance between this unit and a second unit, by sending an optical interrogation signal to the second unit, and receiving an optical response signal from the second unit.
