Abstract

An imaging and pulse detection (IPD) pixel array includes a plurality of imaging pixels arranged in a plurality of rows and columns. Each imaging pixel includes a respective photodetector that outputs signals in response to incident light and input laser pulses. The signals include imaging signals that correspond to the incident light and pulse signals that correspond to the input laser pulses. The IPD array further includes an isolation circuit associated with each of the respective imaging pixels, each isolation circuit outputting filtered output pulse signals in response to receiving the signals from the associated imaging pixel, the filtered output pulse signals corresponding to the pulse signals. The IPD array further includes a single pulse detection circuit that toggles between a charged and uncharged state corresponding to a pulse being received from at least one of the isolation circuits.
