Abstract
A microchannel plate based optical communication receiving system and method of use for extracting embedded information from a covert band of modulated light. The system includes an electrically powered microchannel plate, a sense amplifier in electrical communication with the microchannel plate configured to sense a change in current across a sense resister, a demodulator in electrical communication with the sense amplifier to demodulate the band of modulated light, a data output signal exiting from the demodulator, and a receiver for receiving the data output signal and extracting a piece of covert information.
