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.
