MEMS Mirrors for LiDAR: A Review

Micromachines, 2020
In recent years, Light Detection and Ranging (LiDAR) has been drawing extensive attention both in academia and industry because of the increasing demand for autonomous vehicles. LiDAR is believed to be the crucial sensor for autonomous driving and flying, as it can provide high-density point clouds with accurate three-dimensional information.

Hermetic Package for MEMS Mirror

IMAPSource Proceedings, 2023
Applications for optical scanning and 3D sensing, mostly related to the consumer electronics and automotive markets, are becoming more and more demanding in terms of performance and power consumption. When using a MEMS based Laser Beam Scanning, enclosing the mirrors into a hermetic package helps to address these requirements.

Tunable MEMS axicon mirror arrays

Optics Letters, 2013
Highly aspheric reflective micro-optics for the generation of quasi-nondiffracting beams are of great interest for a wide variety of applications. However, up to now it was impossible to fabricate tunable arrays of these elements. In this Letter, we demonstrate the first array of purely reflective tunable microelectromechanical systems (MEMS ...
