Abstract: An optical detection system for detecting data on the optical mutual coherence function of input field. The system comprising an encoder having similar unit cells, and an array of sensor cells located at a distance downstream of said unit cells with respect to a general direction of propagation of input light. The array defines a plurality of sub-array unit cells, each sub-array corresponding to a unit cell of the encoder, and each sub-array comprising a predetermined number M of sensor elements. The encoder applies predetermined modulation to input light collected by the system, such that each unit cell of said encoder directs a portion of the collected input light incident thereon onto sub-array unit cell corresponding therewith and one or more neighboring sub-array unit cells within a predetermined proximity region. The number M is determined in accordance with a predetermined number of sub-arrays unit cells within the proximity region.

Abstract: There are provided systems and methods for digital optical aberration correction and spectral imaging. An optical system may comprise an optical imaging unit, to form an optical image near an image plane of the optical system; a wavefront imaging sensor unit located near the image plane, to provide raw digital data on an optical field and image output near the image plane; and a control unit for processing the raw digital data and the image output to provide deblurred image output, wherein the control unit comprises a storage unit that stores instructions and a processing unit to execute the instructions to receive the image input and the raw digital data of the optical field impinging on the wavefront imaging sensor and generate a deblurred image based on an analysis of the optical mutual coherence function at the imaging plane.

Abstract: There are provided systems and methods for imaging, measuring an object, and characterizing a sample. An optical, speckle-based imaging system may comprise an illumination unit comprising at least one coherent light source to illuminate a sample; a collection unit for collecting input light from the sample, the collection unit consisting of an imaging optics and a wavefront imaging sensor; and a control unit coupled to the illumination unit and the collection unit for analyzing the input light and generating a speckle wavefront image, wherein the at least one coherent light source is to generate primary speckles in the sample or thereon, and the imaging optics is to capture a secondary speckle pattern induced by the illumination unit in the sample or thereon.
