Abstract
A light ranging and detection (LiDAR) device may combine the transmission of laser pulses. Different trains of pulses from different transmitters may be combined and transmitted to an environment via a common optical path. The laser pulses transmitted from one train of pulses may be in a polarization state that is orthogonal to a polarization state for the laser pulses of the other train of pulses. Reflections for the different trains of pulses may be received via the common optical path and separated according to polarization state. Reflections of the train of pulses may be directed to one receiver and reflections of the other train of pulses may be directed to a different receiver. The transmission delta between the different trains of pulses may be dynamically configured. The pulse repetition rate of each train of pulses may also be configured.
