Experimental study demonstrates real-time two-axis diffractive laser beam steering using dual digital micromirror devices, indicating potential for compact, wide-field optical applications.
We demonstrate two-axis diffractive laser beam steering using two digital micromirror devices. A compact optical relay is designed and implemented. We show the system’s ability to dynamically steer based on camera input in real time. This testbed serves as a platform to enable context-aware ultra-compact wide field-of-view two-axis laser beam steering in a quasi-solid-state modality, which has applications in light detection and ranging, display, and free-space optical communication systems.
