Abstract:
A method may include generating, within a device, separate and discrete wavelengths, and generating light intensity profiles based on an interaction between the separate and discrete wavelengths and a multi-wavelength diffractive optic element. The method may include detecting an object from light reflected from the object using the light intensity profiles. The light intensity profiles may include a shorter range light intensity profile and a longer range light intensity profile, each light intensity profile having different energy per solid angle patterns.
