摘　　要：We demonstrate a blind zone-suppressed and flash-emitting solid-state Lidar based on lens-assisted beam-steering technology.As a proof-of-concept demonstration,with the design of a subwavelength-gap 1D long-emitter array and multiwavelength flash beam emitting,the device was measured to have 5%blind zone suppression,0.06°/point-deflection step,and 4.2μs scanning speed.In time-of-flight ranging experiments,Lidar systems have a field of view of 11.3°×8.1°(normal device)or 0.9°×8.1°(blind-zone suppressed device),far-field number of resolved points of 192,and a detection distance of 10 m.This work demonstrates the possibility that a new integrated beam-steering technology can be implemented in a Lidar without sacrificing other performance.
