Abstract: In one example a method of deceiving an optical augmentation device includes receiving an interrogation beam at an optical system from the optical augmentation device, encoding the interrogation beam with a false signature mis-identifying the optical system, and retro-reflecting the encoded interrogation beam to the optical augmentation device, without retro-reflecting the original interrogation beam.

Abstract: Disclosed is a microwave cavity resonator used as a phase change (phase modulation) to intensity change (intensity or amplitude modulation) converter. Certain aspects and embodiments include resonant circuits, such as a resistor, inductor and capacitor (RLC) circuit. Certain aspects and embodiments convert changes in phase to changes in output voltage to perform analog demodulation of a phase modulated microwave carrier. Certain aspects and embodiments use resonance when the reactive components of the circuit (capacitive and inductive components) are equal in magnitude and 180 degrees out of phase with one another, thereby cancelling out the reactance component of the circuit’s impedance.

Abstract: Methods and apparatus for acoustic to optical communications. In one example, a method includes performing active optical measurements of modulation-based surface deformations at a surface of a body of water using an active optical receiver to produce modulation data, the modulation-based surface deformations being representative of a modulation of a modulated acoustic signal originating beneath the surface of the body of water, between instances of performing the active optical measurements of the modulation-based surface deformations, optically measuring surface conditions of the body of water to produce channel information, and based on the modulation data and the channel information, recovering data encoded in the modulation of the modulated acoustic signal.

Abstract: A transmitter, receiver and transceiver system that may be used for both transmitting and receiving modulated signals are disclosed. The system includes an Electrical-to-Optical (E2O) converter that receives a Radio Frequency (RF) signal and transmits an optical signal and/or an Optical-to-Optical (O2O) that performs a wavelength translation from one wavelength to another wavelength. The Electrical-to-Optical (E2O) converter includes a vapor cell that converts the RF signal to an optical signal.

Abstract: Methods and apparatus for maintaining transmitter-receiver alignment in a free space optical communications system without substantially moving the receiver element and with very little to no imparted momentum, while also allowing for higher tuning speeds and less system complexity than conventional solutions. The methods and apparatus allow for a large field of regard at the optical receiver, without the need for electromechanical gimbals to move the entire receiver unit and without the need for steering mirrors to move and align the incoming optical beam.
