  • Patent number: 10957727
    Abstract: An image sensor may include phase detection pixels that gather phase detection data. The phase detection pixels may be formed in phase detection pixel groups with two or more phase detection pixels covered by a single microlens. Each phase detection pixel may have an asymmetric angular response to incident light. Phase detection pixels may be covered by diffractive lenses. A diffractive lens may cover a phase detection pixel pair to improve angular separation between the pixels. A diffractive lens may partially cover a phase detection pixel in a phase detection pixel pair to shift the angular response and account for an off-axis chief ray angle of the phase detection pixel pair.

  • Patent number: 10958230
    Abstract: In optical receivers, extending the transimpedance amplifier's (TIA) dynamic range is a key to increasing the receiver's dynamic range, and therefore increase the channel capacity. Ideally, the TIA requires controllable gain, whereby the receiver can modify the characteristics of the TIA and/or the VGA to process high power incoming signals with a defined maximum distortion, and low power incoming signals with a defined maximum noise. A solution to the problem is to provide TIA's and VGA's with reconfigurable sizes, which are adjustable based on the level of power, e.g. current, generated by the photodetector.

  • Patent number: 10945326
    Abstract: A configurable light sensor comprising an array of photocells. The light sensor measures ambient light reflected from a surface in area to be monitored. A lens directs the light onto the array of photocells. A microcontroller reads each individual photocell and processes the signals from the photocells according to one or more of the methods disclosed herein. The light sensor is configurable in that the area that monitored by the light sensor is customized to match the area lit by an associated light source. The configuring process defines an active area to be monitored, by determining which subset of photocells in the array, referred to as the active set of photocells, corresponds to the area being illuminated by the light fixture. The light sensor is subsequently able to monitor the defined active area and to report sensor output values based on measurements made from the photocells monitoring the active area.
