Abstract
With the continuing prosperity of LiDAR markets, the demand of
a fast‐scanning, high‐precision and inexpensive LiDAR system is
growing rapidly. In this paper, we disclose a fast‐switchable
ferroelectric liquid crystal Dammann grating and polarization
grating‐based holographic projection and detection system for 3D
imaging devices and LiDAR with an extended field of view. The
field of view of the proposed system can achieve ~80° with <0.5cm
precision at a significantly lower cost. This improvement increases
LiDAR versatility and performance in various scenarios.
