Abstract
An array of MEMS mirrors intercept a laser beam and redirect it toward an environment to be detected. A controller is configured to control the laser and the array of MEMS mirrors to generate a plurality of irregular patterns, such as a Hadamard pattern. The controller controls the laser and the array of MEMS mirrors to generate a plurality of Hadamard patterns on a single scan line at different times, such that all pixel positions in the scan line are impacted by one of the redirected beams from the mirror array at least once. The detected intensities of all the pixel reflections in each pattern are combined to give a total combined intensity for each of the different times. The Hadamard pattern is used to decode the various total combined intensities for a scan line to determine an intensity of each pixel in the scan line.
