    Abstract: To provide an image capture device capable of doing multiple image captures by using multiple image capture units and capable of measuring a distance between each of the image capture units and a target more correctly. An image capture device according to the present invention is an image capture device with multiple image capture units. The image capture device comprises: one light emission unit for distance measurement that emits a reference beam; and the multiple image capture units that capture images of a reflected beam of the reference beam while having common timing of image capture.

    Abstract: A light detection and ranging (“LiDAR”) system includes a coherent light source that generates a frequency modulated optical signal comprising a series of optical chirps. A scanning assembly transmits the series of optical chirps in a scan pattern across a scanning region, and receives a plurality of reflected optical chirps corresponding to the transmitted optical chirps that have reflected off one or more objects located within the scanning region. A photodetector mixes the reflected optical chirps with a local oscillation (LO) reference signal comprising a series of LO reference chirps. An electronic data analysis assembly processes digital data derived from the reflected optical chirps and the LO reference chirps mixed at the photodetector to generate distance data and optionally velocity data associated with each of the reflected optical chirps.

    Abstract: A depth image generating apparatus includes a light source configured to emit light; an optical shutter provided on a path of the light reflected by an object and configured to modulate a waveform of the reflected light by changing a transmissivity of the optical shutter with respect to the reflected light; a driver configured to apply a driving voltage to the light source and a driving voltage to the optical shutter; a temperature measurer configured to measure a temperature of the optical shutter; a controller configured to control driving voltages; and a depth information obtainer configured to generate an image corresponding to the reflected light that passes through the optical shutter, extract a phase difference between a phase of the light emitted by the light source to the object and a phase of the reflected light, and obtain depth information regarding the object based on the phase difference.

    Abstract: Systems, methods, and other embodiments described herein relate to an antenna formed by a silicon photonic two-dimensional grating. In one embodiment, a phased-array light detection and ranging (LIDAR) device includes a phase shifting array that separately shifts a phase of a source light wave to produce separate light waves with distinct phases. The LIDAR device includes optical inputs operably connected with the phase shifting array to receive the separate light waves. The LIDAR device includes a photonic grating operably connected with the optical inputs to receive the separate light waves and having a body that is disposed within a substrate with a face of the body exposed within the substrate. The photonic grating including grating structures exposed within the face. The grating structures redirect the separate light waves to emit the light waves from the photonic grating to form the beam of light.

    Abstract: Spectral imaging sensors and methods are disclosed. One spectral imaging sensor includes a light source, an array of coded apertures, one or more optical elements, and a photodetector. The light source is configured to emit a plurality of pulses of light toward an object to be imaged. The array of coded apertures is positioned to spatially modulate light received from the object to be imaged. The optical elements are configured to redirect light from the array of coded apertures. The photodetector is positioned to receive light from the one or more optical elements. The photodetector comprise a plurality of light sensing elements. The plurality of light sensing elements are operable to sense the light from the one or more optical elements in a plurality of time periods. The plurality of time periods have a same frequency as the plurality of pulses of light.
