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.

Abstract: Techniques are disclosed for improving the quantum efficiency of photocathode devices. The techniques allow for an increase in the optical thickness of the photocathode device, while simultaneously allowing for an increase in the probability of electron escape into the vacuum of the device. The techniques are particularly useful in detector and imaging. In one embodiment, a photocathode device is provided that has an array of corner cubes fabricated in a surface of the photocathode. The corner cube array is made of the same material as the photocathode layer. The device may be, for example, a detector or image intensifier that operates in the UV, visible, and IR light spectrums, and may further include a gain medium, anode, and readout device. Techniques for forming the device are also provided.
