Abstract

Compact, rugged, low power, and affordable laser beamsteering devices are desired to enable light detection and ranging (LiDAR) for advanced driver-assistance systems (ADAS) and ultimately autonomous vehicles. Both optical micro-electro mechanical systems (MEMs) and liquid crystal (LC) clad optical waveguides have been considered. In this paper we will discuss the tradeoffs between these two scanning technologies.
