Low-Cost Solid-State Lidar with Wide Angle of View Using Wavelength Division Multiplexed Laser Array

Abstract

By using wavelength division multiplexed (WDM) laser array developed for optical communication, a novel low-cost solid-state Lidar is designed for TE polarized beams counter-propagating towards each other, which can achieve a large 26-degree angle of view with 60-nm wavelength separation range from WDM laser array.
