Abstract
A Lidar system is provided. The Lidar system includes a laser emitter transmitting a first signal of a first wavelength. The Lidar system includes a filter receiving the first signal. The Lidar system includes a first dichroic filter switch filtering the first signal received by the variable waveplate or other filter. The Lidar system includes a receiver sensor receiving the filtered first signal. The Lidar system includes the laser emitter transmitting a second signal of a second wavelength. The Lidar system includes the variable waveplate or other filter receiving the second signal. The Lidar system includes the first dichroic filter switch filtering the second signal. The Lidar system includes the receiver sensor receiving the filtered second signal. A processor determines a distance of a target based on the received filtered first and second signals.
