Abstract
An optical wireless communications receiver includes a set of photodetectors and signal processing circuitry that receive and process optical communications signals to generate receive data. The receiver includes a spatial light modulator (SLM) and associated SLM controller. The SLM receives an incident optical communications signals from remote optical transmitters and selectively directs the received optical communications signals to the photodetectors to realize an SLM pattern according to SLM control signals from the SLM controller. A system controller establishes the SLM pattern and communicates a description of it to the SLM controller for use in generating the SLM control signals. The receiver may be used in a variety of applications, including so-called visible-light communications or VLC, in which data is transmitted over an optical link using light in the visible spectrum.
