Abstract:
Methods and systems for combining return signals from multiple channels of a LIDAR measurement system are described herein. In one aspect, the outputs of multiple receive channels are electrically coupled before input to a single channel of an analog to digital converter. In another aspect, a DC offset voltage is provided at the output of each transimpedance amplifier of each receive channel to improve measured signal quality. In another aspect, a bias voltage supplied to each photodetector of each receive channel is adjusted based on measured temperature to save power and improve measurement consistency. In another aspect, a bias voltage supplied to each illumination source of each transmit channel is adjusted based on measured temperature. In another aspect, a multiplexer is employed to multiplex multiple sets of output signals of corresponding sets of receive channels before analog to digital conversion.

Claim (Index 1):
A LIDAR measurement system, comprising:\n a first plurality of LIDAR measurement channels each comprising:\n an illumination source that emits a measurement pulse of illumination light when electrically coupled to an electrical power source; \n an illumination driver electrically coupled to the illumination source and the electrical power source, wherein the illumination driver is configured to selectively electrically couple the illumination source to the electrical power source in response to a pulse trigger signal; \n a photodetector that detects an amount of return light reflected from a point in a three dimensional environment in response to the measurement pulse of illumination light; \n a return signal receiver that generates a return signal indicative of the amount of return light detected over time and provides the return signal to a first shared output node of the first plurality of LIDAR measurement channels; \n an analog to digital converter having an input channel, wherein the analog to digital converter receives each return signal of the first plurality of LIDAR measurement channels provided to the first shared output node at the input channel of the analog to digital converter.
