Abstract
A method for scanning a scene is disclosed. According to the method, light is transmitted by a transmitter through a transmitter surface grating array, as a first elliptical pattern in a first lateral direction. Light is received by a receiver through a receiver surface grating array, from an area of a second elliptical pattern. The received light is reflected from the first elliptical pattern. The first elliptical pattern is orthogonal to the second elliptical pattern. The first elliptical pattern overlaps with the second elliptical pattern.
