A system for measuring properties of a medium includes an electromagnetic generator for forming a CW carrier, a digital encoder for forming a digital message, and a modulator for modulating the CW carrier with the digital message to form a digitally modulated CW carrier. The medium provides a channel for propagating the digitally modulated CW carrier. The system further includes a receiver configured to receive the propagated, digitally modulated CW carrier, and a processor for measuring at least one property of the medium. The medium may be disposed within a gaseous atmosphere, a body of water, or a cell of a laboratory.

Method and system for measuring optical properties of a medium using digital communication processing techniques

A light wave rangefinder includes a light transmitting optical system for directing a laser pulse at a target, and a light receiving optical system for receiving reflected light from the target, including a Geiger-mode avalanche photodiode (APD) array and a non-imaging optical device. The non-imaging optical device is positioned between the received reflected light and the APD array, and is configured to uniformly distribute the received reflected light across the APD array. The APD array is uniformly illuminated by a single received reflected laser pulse, producing a plurality of Geiger-mode avalanche events.

Photon-counting, non-imaging, direct-detect LADAR

A method of tracking a target includes: (a) receiving energy from the target at a plurality of spatial orientations; (b) processing the received energy; (c) evaluating a penalty function at each of the plurality of spatial orientations; (d) selecting a new spatial orientation based on the evaluation; and (e) orienting a receiver to receive energy from the target at the new spatial orientation.
