Abstract
A method for enabling light detection and ranging (LiDAR) scanning is provided. The method is performed by a system disposed or included in a vehicle. The method comprises receiving a first laser signal. The first laser signal has a first wavelength. The method further includes generating a second laser signal based on the first laser signal. The second laser signal has a second wavelength. The method further includes providing a plurality of third laser signals based on the second laser signal; and delivering a corresponding third laser signal of the plurality of third laser signals to a respective LiDAR scanner of the plurality of LiDAR scanners. Each of the LiDAR scanners are disposed at a separate location of the vehicle such that each of the LiDAR scanners is capable of scanning a substantial different spatial range from another LiDAR scanner. LiDAR systems can use multi-wavelength to provide other benefits as well.
