  • Patent number: 11914076
    Abstract: LiDAR system and methods discussed herein use a dispersion element or optic that has a refraction gradient that causes a light pulse to be redirected to a particular angle based on its wavelength. The dispersion element can be used to control a scanning path for light pulses being projected as part of the LiDAR's field of view. The dispersion element enables redirection of light pulses without requiring the physical movement of a medium such as mirror or other reflective surface, and in effect further enables at least portion of the LiDAR's field of view to be managed through solid state control. The solid state control can be performed by selectively adjusting the wavelength of the light pulses to control their projection along the scanning path.
