Abstract
A receiver, method, terminal device, visible light transmissive structure and system for decoding light signals and light signals received in an area of overlap of light rays emanating from different lighting devices, each transmitting unique ID data. Light rays () entering the receiver () are optically spread apart in longitudinal direction (x) of an array of photodetectors (). The thus spread light rays () are optically diverged and spread further over the radiant active surface () of a particular photodetector (-), thereby optimizing the amount of light received at a respective photodetector (-).
