Microchannel plate based optical communication receiver system

摘要

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.

主权项

1. A microchannel plate based optical communication receiving system comprising:
an optical receiver providing a stream of modulated electrons; an electrically powered microchannel plate, the plate having a first current prior to receiving the stream of modulated electrons and having a second current as the electrons pass through the microchannel plate; a sense amplifier and filter in electrical communication with the microchannel plate sensing the change in current from the first to second current, and the filter is selectively set to a modulation frequency band pass, wherein the modulation frequency band pass is similar to the frequency of the modulated electrons moving through the microchannel plate; and a demodulator in electrical communication with the sense amplifier to demodulate the electrons; a data output signal exiting from the demodulator; and a receiver for receiving the data output signal and extracting a piece of information.
