摘要： A variable delay device is connected to a photosensor of a time-of-flight gamma ray detection system and includes a substrate on which a plurality of conductive pins are affixed. A first terminal connected to a first of the plurality of pins and a second terminal connected to the second of the plurality of pins are also affixed to the substrate. A jumper electrically connects the plurality of pins at a predetermined distance relative to the substrate, and a time delay of the variable delay device is determined based on the electrical path between the first and second terminals formed by the plurality of pins and the jumper.

摘要： The present invention provides an optical filter assembly that reduces the phase and amplitude noise of a detection laser used to detect ultrasonic displacements. The filtered detection laser is directed to the surface of a remote target. Ultrasonic displacements at the surface scatter the filtered detection laser. Collection optics then gather phase modulated light scattered by the surface and direct the phase modulated light to an optical processor to produce a signal representative of the ultrasonic displacements with an improved SNR. Additional processors may determine the structure of the remote target.
