Abstract: 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.

Abstract: Image-sensing devices include odd-symmetry gratings that cast interference patterns over a photodetector array. Grating features offer considerable insensitivity to the wavelength of incident light, and to the manufactured distance between the grating and the photodetector array. Photographs and other image information can be extracted from interference patterns captured by the photodetector array. Images can be captured without a lens, and cameras can be made smaller than those that are reliant on lenses and ray-optical focusing.

Abstract: The embodiments herein describe technologies of cryogenic digital systems with a power supply located in an ambient temperature domain and logic located in a cryogenic temperature domain. A pair of conductors is operable to carry current with a voltage difference between the power supply and the logic. The pair of conductors includes a first portion thermally coupled to a temperature-regulated or temperature-controlled intermediate temperature domain. The intermediate temperature domain is less than the ambient temperature domain and greater than the cryogenic temperature domain.

Abstract: A user interface includes both a touchscreen for tactile input and one or more lensless optical sensors for sensing additional, remote gestures. Users can interact with the user interface in a volume of space near the display, and are thus not constrained to the relatively small area of the touchscreen. Remote hand or face gestures can be used to turn on or otherwise alter the tactile user interface. Shared user interfaces can operate without touch, and thus avoid cross-contamination of e.g. viruses and bacteria.

Abstract: An optical phase grating produces an interference pattern rich in intensity and spatial-frequency information from the external scene. The grating includes an odd number of repeated sets of adjacent horizontal portions, separated by steps, that fill an area that radiates outward from a central region. At a given distance from the central region and within the area of the phase grating, each of the first horizontal portions is of a first width that differs from a second width of the adjacent second horizontal portions. The interference patterns produced by the grating can be processed to extract images and other information of interest about an imaged scene.

Abstract: An infrared imaging system combines a low-resolution infrared camera with a high-resolution visible-light camera. Information extracted from images taken using the visible-light camera is combined with the low-resolution infrared images to produce an infrared image with enhanced spatial details. The process of extracting the information from the visible image adjusts the quantization level of the visible-light image to scale visible objects to match objects identified in the infrared image.

Abstract: An imaging system includes multiple diffractive optical gratings disposed over a two-dimensional array of photosensitive pixels. The different gratings present different patterns and features that are tailored to produce point-spread responses that emphasize different properties of an imaged scene. The different responses are captured by the pixels, and data captured from the responses can be used separately or together to analyze aspects of the scene. The imaging systems can include circuitry to analyze the image data, and to support modes that select between point-spread responses, selections of the pixels, and algorithms for analyzing image data.
