A spatial light modulator (SLM) is a large-scalephase-control arraywith a working principle analogous to that ofmicrowave phased array antennas . By precisely controlling the phase of the light beam emitted from each coherent combining unit, it enables accurate regulation of the beam’s propagation direction, achieving high-precisiontwo-dimensional (2D) optical scanning . Furthermore, it can simultaneously generate multiple light beams to perform real-time tracking of moving targets.

Theoptical phased array (OPA)technology based on spatial light modulators features the advantages ofno mechanical inertia , high scanning accuracy, and high resolution. In recent years, it has emerged as aresearch hotspotin the field of lidar.
