Abstract:
A system and a method for producing an adjustable light pattern are provided herein. The system may include: a transmitter configured to illuminate a scene with a patterned light being adjusted based on predefined criteria; a receiver configured to receive reflections of the adjusted patterned light; and a computer processor configured to control the adjustment of the patterned light and further analyze the received reflections, to yield a depth map of objects within the scene, wherein the transmitter may include: a light source configured to produce a light beam; a first reflector tiltable approximately along a line on an x-y plane in a Cartesian x-y-z coordinate system; and a second reflector tiltable along a z-axis in said coordinate system, wherein the reflectors are tilted along their respective axes back and forth so as to divert the light beam for creating the adjusted patterned light.
