摘要： A system to generate image representations includes a first objective that receives a first light beam emitted from a sample and a second objective that receives a second light beam emitted from the sample, where the first light beam and the second light beam have conjugate phase. The system also includes a first diffractive element to receive the first light beam and separate it into a first plurality of diffractive light beams that are spatially distinct, and a second diffractive element to receive the second light beam and separate it into a second plurality of diffractive light beams that are spatially distinct. The system further includes a detector that receives the first and second plurality of diffractive light beams. The first plurality of diffractive light beams and the second plurality of diffractive light beams are simultaneously directed and focused onto different portions of an image plane of the detector.

摘要： Motion contrast depth scanning is disclosed herein. A disclosed example apparatus includes an illumination source that is to provide at least one of spatial or temporal changes to light emitted from the illumination source to a scene. The example apparatus also includes a motion contrast sensor, where pixels of the motion contrast sensor are to detect changes corresponding to the scene, and where the motion contrast sensor is to report measurements when a pixel change exceeds a threshold. The example apparatus further includes a processor to determine at least one of a reflectance, a depth, or movement of the scene based on the reported measurements by the motion contrast sensor.

摘要： A three-dimensional (3D) display system includes a reference spatial light modulator configured to generate a reference wavefront. The system also includes an object spatial light modulator configured to generate an object wavefront. The system further includes a Hogel basis display positioned between the reference spatial light modulator and the object spatial light modulator. The Hogel basis display is configured to receive the reference wavefront and the object wavefront. The Hogel basis display is also configured to generate a light field based at least in part on interference between the reference spatial light modulator and the object spatial light modulator.

摘要： Systems, methods, and computer readable media for hyperspectral imaging are provided. An example hyperspectral imaging sensor system to identify item composition includes an imager to capture hyperspectral imaging data of one or more items with respect to a target. The example includes a sensor to be positioned with respect to the target to trigger capture of the image data by the imager based on a characteristic of the target. The example includes a processor to prepare the captured imaging data for analysis to at least: identify the one or more items; determine composition of the one or more items; calculate an energy intake associated with the one or more items; and classify the target based on the energy intake.
