  • Patent number: 11404455
    Abstract: There is provided an imaging apparatus including a first imaging element and a second imaging element configured to perform imaging in the same direction. The second imaging element is different in pixel arrangement between a central part and a non-central part, such that the pixels in the non-central part are more sensitive than the pixels in the central part. Image signals from the non-central part of the second imaging element are used to correct for shading (vignetting) in image signals from the first imaging element.

  • Patent number: 11402266
    Abstract: The present disclosure provides a method and system for improving a counting rate of a superconducting nanowire single photon detector. The method includes: coupling an electrical attenuator in series with an output end of the superconducting nanowire single photon detector; the electrical attenuator includes an input end and an output end, and the input end of the electrical attenuator is coupled with the output end of the superconducting nanowire single photon detector. The present disclosure couples the electrical attenuator in series with the output end of the superconducting nanowire single photon detector. Since the configuration of the electrical attenuator is a resistor network, it can act as a series resistor and can also reduce the response pulse amplitude of the superconducting nanowire single photon detector. The present disclosure can improve the counting rate of the superconducting nanowire single photon detector, while keeping the detection efficiency high.

  • Patent number: 11391623
    Abstract: Methods for design and production of highly sensitive active and passive light detecting devices and systems. Orders of magnitude improvement in optical signal detection is made possible in high noise or low contrast scenes. The current invention creates a small spectral difference between two parts of a split light stream. When recombined, the altered light streams partially correlate, and that generates fall amplitude signal oscillation at a frequency that depends on the constituent spectrum. The full amplitude signals and spectrum dependent oscillation make signal discrimination much better than intensity-only methods. The effect of read noise, amplifier noise, dark current noise, and thermal noise due to photo detector shunt resistance, become less important when compared to light detection using prior art methods.
