Abstract
The present invention includes embodiments of optical receivers, communication systems and communication platforms for receiving electromagnetic radiation (EMR) signals from a plurality of sources and/or directions. An embodiment of an optical receiver, a communication system, or a communication platform may include a Lüneburg lens. The Lüneburg lens allows incoming EMR to be directed to a photodetector. A processor in communication with the photodetector may be configured for calculating power gradient of energy density of the inbound optical signals, isolating discrete inbound optical signals, determining direction of the inbound optical light signals and gathering information transmitted in the inbound optical light signals.

An optical communication receiver, comprising:
- a photodetector having a sensor plane, the photodetector configured to receive incident optical light signals and detect optical signal energy density corresponding to x-y locations along the sensor plane;
- a Lüneburg lens adjacent to the photodetector and configured to direct incident optical light signals onto the sensor plane of the photodetector;
- and
- a processor in communication with the photodetector configured for calculating power gradient of the optical signal energy density, isolating discrete signals, determining direction of the incident optical light signals and gathering information transmitted in the incident optical light signals.
An optical communication system comprising:
- an optical receiver configured to receive inbound optical signals, the optical receiver comprising a Lüneburg lens;
- and
- a processor in communication with the optical receiver and configured for calculating power gradient of energy density of the inbound optical signals, isolating discrete inbound optical signals, determining direction of the inbound optical light signals and gathering information transmitted in the inbound optical light signals.
A communication platform, comprising:
- at least one optical communication system, comprising:
- an optical receiver configured to receive inbound optical signals, the optical receiver comprising a Lüneburg lens;
- and
- a processor in communication with the optical receiver and configured for calculating power gradient of energy density of the inbound optical signals, isolating discrete inbound optical signals, determining direction of the inbound optical light signals and gathering information transmitted in the inbound optical light signals.
