Like any mirrors, MEMS-based mirrors are used in optical beam-steering applications, i.e. to deflect optical beams or images from one point to another in a controlled fashion. By moving the mirror in a tip-tilt fashion optical beams can be deflected to new, arbitrary positions in space. Applications include 3D scanning and object digitization, projection displays, laser marking and printing, image scanning, position-tracking and sensing, rapid prototyping, Light Detection And Ranging (LIDAR), and various biomedical imaging applications such as optical coherence tomography (OCT)-based imaging, among many others.
