Spatially-chirped optical phased array design and its 10-m LiDAR operation

Not Accessible

Your library or personal account may give you access

Abstract

Novel optical phased array design based on spatially-chirped spacing is presented for solid-state beam steering. Its 128-channel implementation achieved 2.1-dB higher side- mode suppression ratio compared to previous results. 10-m 3D depth imaging was also demonstrated.
