Abstract

An optical system for scanning angle amplification in tunable laser based all-solid lidar is theoretically analyzed and experimentally demonstrated with θ=51° when tuning the wavelength from 1531.2nm to 1566.6nm. We have achieved 22 points beam-steering which is identical to the tunable laser channels. The device has several microseconds beam switching speed and 1.4° beam divergence. The size of the device is compact which is only 5cm×4.5cm×1.8cm, and the total system is low-cost.
