Abstract
An optical sensor system for communication and pointing may include an optical sensor having photocells arranged in an array configured to receive at least one optical signal, and the optical sensor, in response to the optical signal, generating a first output signal and a second output signal, wherein the first output signal represents instantaneous photon flux of the received optical signal and the second output signal represents a derivative of the instantaneous photon flux of the received optical signal where the optical sensor operates as a dual communication and pointing sensor.
