Patent number: 11921254Abstract: An optical seismic surveying system including, a multibeam laser source including a plurality of laser-sources, a Diffractive-Optical-Element (DOE), an imager and a processor. The laser-sources direct respective laser-beams toward a single common focal point. The DOE is located at a single common focal point and configured to split each laser-beam into a plurality of laser-beams, toward an instantaneous area of interest. The laser-beams impinging on the instantaneous area of interest produce a laser spot assemblage including a plurality of laser spots. The imager acquires a plurality of defocused images of speckle patterns produced by diffused reflections of the laser spots. The speckle pattern correspond to a respective laser spot and thus to a respective sensing point in the instantaneous area of interest.Type: GrantFiled: February 9, 2022Date of Patent: March 5, 2024Assignees: ELBIT SYSTEMS LAND AND C4I LTD., SOREQ NUCLEAR RESEARCH CENTERInventors: Aner Lev, Shai Mordechai Butzin, Barak Alfassi, Alon Refael Heimer

Patent number: 6738653Abstract: Method and apparatus for determining the oxygenation level of hemoglobin in a probed region of the human body. A probed region of the body is irradiated with diffuse light, the frequency of which is shifted with ultrasound focused at the probed region.
