Abstract:
Methods and systems for performing three dimensional LIDAR measurements with an integrated LIDAR measurement device are described herein. In one aspect, a return signal receiver generates a pulse trigger signal that triggers the generation of a pulse of illumination light and data acquisition of a return signal, and also triggers the time of flight calculation by time to digital conversion. In addition, the return signal receiver also estimates the width and peak amplitude of each return pulse, and samples each return pulse waveform individually over a sampling window that includes the peak amplitude of each return pulse waveform. In a further aspect, the time of flight associated with each return pulse is estimated based on a coarse timing estimate and a fine timing estimate. In another aspect, the time of flight is measured from the measured pulse due to internal optical crosstalk and a valid return pulse.

Claim (Index 22):
An integrated LIDAR measurement device, comprising:\n an illumination source mounted to a printed circuit board; an illumination driver integrated circuit (IC) mounted to the printed circuit board, the illumination driver IC selectively couples the illumination source to an electrical power source in response to a pulse trigger signal, causing the illumination source to emit a measurement pulse of illumination light; a photodetector mounted to the printed circuit board, the photodetector configured to detect a first amount of the measurement pulse of illumination light due to crosstalk between the illumination source and the photodetector and a valid return pulse of light reflected from a location in a surrounding environment illuminated by a second amount of the measurement pulse; and a return pulse receiver IC mounted to the printed circuit board, the return pulse receiver IC configured to estimate a time between an instance when the first amount of the measurement pulse of illumination light due to crosstalk is detected and an instance when the valid return pulse of light is detected.
