Abstract: Provided is a gyroscope stabilized gimbal assembly for collecting and timestamping video data and laser measurement data. The assembly can be used on multiple platforms and provides an ISR video camera system and one or more laser measurement devices, including photodetectors, thermopiles, filters, and analog to digital converters. The components are mounted to a bracket that can be installed and removed from the assembly to collect/record measurement data from the devices interacting with the laser beam. A processor collects and records measurement data from the devices interacting with the laser beam and calculates optical power data, irradiance data, and wavelength data. A storage device stores a first set of data comprising video data from said camera system and a second set of data comprising optical power data, irradiance data, and wavelength data, wherein said first and second set of data are timestamped, separated, and not comingled.

Abstract: The disclosure relates to a light propagation time pixel, comprising modulation gates and integration nodes which are arranged on the upper face of a photosensitive semiconductor region. The photosensitive semiconductor region is designed as an N-epitaxy and is delimited laterally and/or at the corners by p-doped vertical p-structures. A buried layer with a p-doping adjoins the lower face of the photosensitive semiconductor region, and the vertical p-structures are in electric contact with the buried layer.
Abstract: Methods and systems for imaging a target. In some examples, a system includes an optical modulator configured for applying, at each time of an exposure window, a respective optical modulation pattern to a received image of the target to output a modulated image. The system includes a camera configured for capturing a single image frame for the exposure window by receiving, at each of time, the modulated image of the target. The system includes a demodulator implemented on a computer system and configured for demodulating the single image frame based on the optical modulation patterns to recover a number of recovered image frames each depicting the target at a respective recovered time within the exposure window.

Abstract: The present technology relates to an image sensor and an electronic apparatus which enable higher-quality images to be obtained. Provided is an image sensor including a plurality of pixels, each pixel including one on-chip lens, and a plurality of photoelectric conversion layers formed below the on-chip lens. Each of at least two of the plurality of photoelectric conversion layers is split, partially formed, or partially shielded from light with respect to a light-receiving surface. The pixels are phase difference detection pixels for performing AF by phase difference detection or imaging pixels for generating an image. The present technology can be applied to a CMOS image sensor, for example.
Abstract: An optical emitter-receiver module includes a light source, a photodetector and a fiber. The light source emits an emitted beam. The fiber includes a core and an optical axis. The fiber has an outer surface, inclined at an angle of 45° with respect to the optical axis, having a mirror. The fiber has a notch, extending to the core of the fiber and having a face having a dichroic filter for reflecting a received beam. The light source is arranged relative to the mirror so that the emitted beam is reflected by the mirror and transmitted in the fiber. The photodetector and the face of the notch are positioned so that the received beam reflected by the dichroic filter is directed towards the photodetector.
