The optical phased array (OPA) is a high-speed and compact device for optical wavefront generation and beam steering, with potential applications in LiDAR and single-pixel imaging. However, traditional OPAs have faced the challenge of low resolution due to the complexity of their control. In this study, we experimentally demonstrated high-resolution imaging using a non-redundant OPA, antennas of which are non-redundantly arranged, and successfully achieved over 10,000 imaging points using 127 phase shifters without wavelength sweeping.
