Patent attributes
The present disclosure relates to multi-channel optical transmitter modules, lidar systems, and methods that involve micromirror devices. An example optical transmitter module includes at least one light-emitter device and a plurality of micromirror devices optically-coupled to the at least one light-emitter device. The at least one light-emitter device is configured to emit respective light beams toward an environment via the micromirror devices. The micromirror devices are configured to deflect the light beams. The optical transmitter module also includes a controller having at least one processor and a memory. The controller is configured to carry out operations. The operations include receiving information indicative of a retroreflector object in the environment. The operations include, based on the received information, causing at least one micromirror device of the plurality of micromirror devices to deflect at least one light beam so that the at least one light beam does not interact with the retroreflector object.
