Abstract: An optical beam combiner is provided, which allows efficient collection of light for various applications: non-line of sight and free space optical communications, remote sensing, optical imaging and others. A multitude of optical beam portions is captured by a space diversity receiver that includes an optical beam combiner, which has a tree-like topology with interconnected waveguides, electro-optic phase shifters, and directional couplers. For each of the beam portions the phase of the phase shifter and the coupling ratio of coupler in the optical beam combiner are tuned sequentially to maximize the final output power in the final optical waveguide. A portion of the final output beam is used for the power detection and forming a feedback signal for the phases and coupling ratios adjustment. The data or information is recovered from the received final optical beam using coherent detection.

Abstract: A method and system for high Z substance revealing using muon detection technique is presented. Natural muon coordinate and incidence angle are measured above and below the interrogated volume. The data on muons trajectory change caused by the presence of high Z material and the muons time of flight between the upper and lower muon detectors are used for the decision making on the presence of a nuclear substance inside the volume. The system is adapted for performing measurements on moving objects such as moving trucks.

Abstract: A photo-thermal, interferometric spectroscopy system is disclosed that provides information about a chemical at a remote location. A first light source assembly is included that emits a first beam. The first beam has one or more wavelengths that interact with the chemical and change a refractive index of the chemical. A second light source produces a second beam. The second beam interacts with the chemical resulting in a third beam with a phase change that corresponds with the change of the refractive index of the chemical. A detector system is positioned remote from the chemical to receive at least a portion of the third beam. The detector system provides information on a phase change in the third beam relative to the second beam that is indicative of at least one of, absorption spectrum and concentration of the chemical.
