    摘要： The present disclosure provides a method for improving capability of resisting image noise of a co-phasing system of a dispersed fringe sensor. The method comprises the following steps: carrying out a coarse co-phasing adjustment by utilizing the dispersed fringe sensor until the coarse co-phasing is stabilized in a closed loop; collecting a two dimensional dispersed fringe image by the dispersed fringe sensor; superposing the dispersed fringe image along a dispersed direction so as to convert the two dimensional dispersed fringe image to a one dimensional image along an interferential direction; extracting peak values of the main peak, a left side lobe and a right side lobe of the one dimensional image along the interferential direction, and calculating corresponding piston error value of the image by carrying out a Left-subtracting-right LSR algorithm on these peak values.

    摘要： A sensing device with an odd-symmetry grating projects near-field spatial modulations onto a closely spaced photodetector array. Due to physical properties of the grating, the spatial modulations are in focus for a range of wavelengths and spacings. The spatial modulations are captured by the array, and photographs and other image information can be extracted from the resultant data. Used in conjunction with a converging optical element, versions of these gratings provide depth information about objects in an imaged scene. This depth information can be computationally extracted to obtain a depth map of the scene.

    摘要： Electro-optical sighting systems and methods are provided. One example includes a optical transmitter configured to emit an infrared beam along an optical path toward a target, a beam director positioned in the optical path and having a plurality of optical elements configured to direct the infrared beam and to collect reflected infrared radiation from reflection of the beam from the target, a focal plane array detector configured to receive reflected infrared radiation from the beam director, an optical phased array (OPA) positioned in the optical path between the optical transmitter and the beam director, and a controller operatively coupled to the OPA and configured to direct the OPA to defocus the infrared beam to broaden a field of view of the optical transmitter for active illumination, and focus the infrared beam to narrow the field of view of the optical transmitter for range determination and/or target designation.
