FLAT OPTICS WITH PASSIVE ELEMENTS FUNCTIONING AS A TRANSFORMATION OPTICS AND A COMPACT SCANNER TO COVER THE VERTICAL ELEVATION FIELD-OF-VIEW

A 360-degree Field-Of-View LIDAR is capable of delivering light to a target and detecting light reflected off a given target in order to determine the distance from the light source to the target over the entire 360-degree surrounding. The LiDAR has such capability because of the built-in light sour...

Zusammenfassung:	A 360-degree Field-Of-View LIDAR is capable of delivering light to a target and detecting light reflected off a given target in order to determine the distance from the light source to the target over the entire 360-degree surrounding. The LiDAR has such capability because of the built-in light source, detector, and scanner which can steer the light source and the detector to cover the entire azimuthal angles. In some embodiments, the LiDAR has the unique arrangement of the light source and the detector which are fixed to a base while the rotating scanner and a flat optics contains motor, scanning mirror, and metasurface/flat optics to project the light source to its surroundings as well as receiving light from surroundings. In particular, flat optics perform the function of transforming the reference frame and beam steering in the vertical direction.
