  • Patent number: 10634559
    Abstract: A spectrally-scanned hyperspectral EO sensor trades the temporal properties of spectral information content for instantaneous situation awareness by capturing an image frame and scanning the spectral scene (wavelength) to build up spectral content. The objective optical system, preferably including a chromatic aberration enhancing device, separates spectral components of the incident radiation. A focus cell is used to adjust a relative axial focus position of the objective optical system with respect to a detector to at least two different axial focus positions to adjust the image position and read out an image frame for a spectrally-weighted component. A processor computes a relative spatial image contrast from a plurality of image frames at different wavelengths as a function of encoded focus cell position. A mechanism may be configured to move the enhancing device in and out of the optical path to form a dual gray-scale and hyperspectral EO sensor.

  • Patent number: 10609266
    Abstract: A camera system comprises illumination and optical components that manage illumination from the illumination source to the camera sensor in a highly efficient manner to image a wide field of view. The camera sensor comprises a modular compound imaging lens and a corresponding illuminator. The illuminator is capable of emitting a field of illumination that is wide in one plane (e.g., the tangential plane) and relatively narrow in the orthogonal plane (e.g., the sagittal plane). The modular compound lens receives scattered light from the viewing field and focuses the light to one or more imaging sensors (e.g., 3D imaging sensors). The modular lens images a wide field of view substantially equal to the field of illumination of the illuminator and is oriented such that the field of view of the lens substantially overlaps the field of illumination of the illuminator, yielding a high collection efficiency.

  • Patent number: 10594973
    Abstract: An image sensor architecture with multi-bit sampling is implemented within an image sensor system. A pixel signal produced in response to light incident upon a photosensitive element is converted to a multiple-bit digital value representative of the pixel signal. If the pixel signal exceeds a sampling threshold, the photosensitive element is reset. During an image capture period, digital values associated with pixel signals that exceed a sampling threshold are accumulated into image data.
