  • Enhanced pixel for wavefront sensing
    Patent number: 9939324
    Abstract: A wavefront sensing pixel is provided. The wavefront sensing pixel includes a low-pass filter filtering a charge signal from a photodetector and outputting a control signal when low-frequency signals are detected in the charge signal, and a control device to control flow of the charge signal past the control device based on whether a low-frequency signal is detected in the charge signal. The wavefront sensing pixel further includes a low-frequency signal path that receives a flow of signals that flow past the control device, and a high-frequency signal path independent of the low-pass filter and the control device, the high-frequency signal path receiving high-frequency signals included in the charge signal.

  • Integrating pixels and methods of operation
    Patent number: 9686490
    Abstract: A pixel cell includes a first integration capacitor, a second integration capacitor, a photo detector and a transistor. The first integration capacitor includes a first lead operatively coupled to the photo detector. The second integration capacitor includes a first lead. The transistor is operatively coupled between the leads of the first and second integration capacitors for enabling current flow between the photo detector and the second integration capacitor only once a threshold voltage is met on the first integration capacitor.
