  • Patent number: 11450779
    Abstract: An apparatus, system, and method for detecting light having a specified or first wavelength. The apparatus includes a substrate that generates charge separation in the presence of light having the first wavelength. An active material is deposited onto the substrate. The active material is configured to conduct current in the presence of light having a second wavelength. Two electrodes are connected to the active material. Light having the second wavelength is constantly applied to the active material and the current is monitored via the electrodes. The active material will conduct zero or minimal current via the electrodes if the substrate does not generate charge separation. Detection the presence of light having the first wavelength may be detected upon the detection of current via the two electrodes. The first wavelength may be non-visible light and the second wavelength may be visible light.

    Abstract: A measured photo-event array is converted from two spatial coordinates and one temporal coordinate into three spatial coordinates for real-time imaging. Laser light pulses illuminate at least one object, and a Geiger-mode avalanche photodiode array receives photons from laser light reflected off the object. For each pulse of the laser light, the GMAPD outputs a first array of photo-events representative of reflected photons.
