Abstract: A method includes providing outgoing optical signals for transmission by a monostatic optical terminal using multiple transmit channels and providing incoming optical signals obtained by the monostatic optical terminal to multiple receive channels. The method also includes using a polarization beam splitter/combiner to combine the outgoing optical signals into a combined outgoing optical signal and to split a combined incoming optical signal into the incoming optical signals. The method further includes using at least one feedback loop to adjust an aim or path of at least one of the outgoing optical signals or at least one of the incoming optical signals. The method may optionally include using an optical element to convert polarizations of the combined outgoing optical signal in order to generate an output signal and to convert polarizations of an input signal in order to generate the combined incoming optical signal.

Abstract: An apparatus includes a sensor having an array of detectors. The sensor is configured to assign multiple detectors to a detector group corresponding to a block pixel. The sensor is also configured, for each frame of a set of frames, to apply a specified one of a set of mask patterns in order to select outputs of the detectors in the detector group and aggregate the selected outputs of the detectors in the detector group to determine pixel information for the block pixel. The apparatus also includes at least one processor configured to generate the frames using the pixel information for the block pixel, and upscale the portion of the at least one of the frames using the set of mask patterns to identify native pixels within the block pixel.

Abstract: Optical signal receivers, systems, and methods of operating the same include a non-line of sight optical signal receiver configured to receive and detect a complex modulated optical signal through a non-line of site propagation path from an optical transmitter, comprising an optical resonator configured to receive the complex modulated optical signal through the non-line of sight propagation path, and to convert the complex modulated optical signal to an intensity modulated signal, and a detector configured to convert the intensity modulated signal into an electrical signal, the electrical signal having an amplitude indicative of an intensity of the intensity modulated signal from the optical resonator, and to provide a detected signal.

Abstract: A method includes generating a first optical signal containing doublet pulses. Each doublet pulse includes a first pulse and a second pulse. The second pulses of the doublet pulses are in quadrature with the first pulses of the doublet pulses. The method also includes transmitting the first optical signal towards a target and receiving a second optical signal containing reflected doublet pulses from the target. Each reflected doublet pulse includes a first reflected pulse and a second reflected pulse. The method further includes performing in-phase and quadrature processing of the first and second reflected pulses and identifying one or more parameters of the target based on the in-phase and quadrature processing.
