ADAPTIVE COMMUNICATIONS FOCAL PLANE ARRAY
First Claim
1. A method, comprising:
- collecting optical flux received at a plurality of optical detectors;
determining whether the collected optical flux received at one or more of the plurality of optical detectors is associated with one or more optical beams being emitted by an optical transmitter of an optical communications network;
suppressing output signals from those optical detectors of the plurality of optical detectors that are not receiving optical beams from the optical transmitter of the optical communications network;
extracting optical data sequences from output signals of those optical detectors of the plurality of optical detectors that are receiving optical beams from the optical transmitter of the optical communications network; and
presenting information obtained from the optical data sequences extracted from output signals of those optical detectors that are receiving optical beams from the optical transmitter of the optical communications network.

Abstract
Adaptive communications focal plane arrays that may be implemented in, e.g., a specially-configured camera that can be utilized to receive and/or process information in the form of optical beams are presented. A specialized focal plane array (FPA) having a plurality of optical detectors is utilized, where one or more optical detectors are suppressed such that data is not allowed to be output from the one or more suppressed optical detectors, and only a significantly smaller number or subset of optical detectors receiving optical beams are allowed to output data. In this way, the rate at which data is to be output by an adaptive communications FPA (ACFPA) can be significantly reduced.
