Abstract
A LiDAR system comprising a laser source configured to output electromagnetic radiation based on an input signal and circuitry configured to supply the input signal to the laser source to control electromagnetic radiation output by the laser source, such that the laser source outputs a waveform including a plurality of output states. The laser source outputs electromagnetic radiation having a particular wavelength during the output states. Each of the plurality of output states is separated in time from neighboring output states of the plurality of output states by a time span. The particular wavelength of the electromagnetic radiation for a first output state of the plurality of output states is different from the particular wavelength of electromagnetic radiation for a second output state of the plurality of output states.
