Micro Electro Mechanical System (MEMS) spatial light modulators enables adaptive and fast beam and image steering. For lidar applications, Texas Instruments Phase Light Modulator (TI-PLM) is paired with real-time calculation and display of Computer Generated Holograms (CGH) by CUDA-OpenGL interoperability assisted by YOLOv4-tiny network model for object detection and recognition. The real-time object recognition, CGH calculation, and display framework replaces conventional raster scanning with camera-input based and foveated beam steering while having a beam scan rate beyond the frame rate of TI-PLM. For Augmented Reality (AR) application, the same framework is used for image steering based on gaze information of eye. With Texas Instruments Digital Micromirror Device (TI-DMD), image is steered into a part of field of view by following movement of eye. The diffractive image steering enabled by TI-DMD increases FOV while not sacrificing resolution of the image displayed.
