Abstract
Optical systems including Microelectromechanical System devices (MEMS) phased-arrays and methods for operating the same to improve contrast are provided. Generally, the system includes a light source, illumination optics, and MEMS phased-arrays operable to receive a light-beam from the illumination optics and to project light onto a far-field scene and to steer an area of illumination over the far-field scene by modulating phases of at least some light of the light-beam received from the illumination optics. The illumination optics are operable to illuminate the MEMS-phased arrays with a light-beam having a Gaussian-profile to minimize side-lobes with respect to a main-lobe in an emission profile of light reflected from the far field scene in response to the projected light. In some embodiments the system is or is included in a Light Detection and Ranging system.
