Abstract:
A lidar system includes a transmitter that encodes successive transmit pulses with different pulse characteristics and a receiver that detects the pulse characteristics of each received (scattered or reflected) pulse and that distinguishes between the received pulses based on the detected pulse characteristics. The lidar system thus resolves range ambiguities by encoding pulses of scan positions in the same or different scan periods to have different pulse characteristics, such as different pulse widths or different pulse envelope shapes. The receiver includes a pulse decoder configured to detect the relevant pulse characteristics of the received pulse and a resolver that determines if the pulse characteristics of the received pulse matches the pulse characteristics of the current scan position or that of a previous scan position.

Claim (Index 32):
A range detection system, comprising:\n a light source capable of emitting light pulses; a controller configured to direct a pulse encoder to encode a first emitted light pulse with a first set of pulse characteristic values and a second emitted light pulse with a second set of pulse characteristic values, wherein the first set and second set of pulse characteristic values are different; a scanner configured to direct the first emitted light pulse at a first scan position within a two dimensional field of regard and to direct the second emitted light pulse at a second scan position within the two dimensional field of regard, each scan position defined by a different set of vector coordinates; a detector configured to detect a light pulse scattered by a remote target and to produce electric signals indicative of the scattered light pulse; a pulse decoder coupled to the detector that detects one or more pulse characteristic values of the scattered light pulse using the electric signals a resolver that determines if the detected one or more pulse characteristic values match the first set of pulse characteristic values of the first emitted pulse or the second set of pulse characteristic values of the second emitted pulse, and a range detector that calculates a range to the remote target based on the first emitted light pulse if the detected pulse characteristic values match the first set of pulse characteristic values or on the second emitted light pulse if the detected pulse characteristic values match the second set of pulse characteristic values.
