Abstract
This paper reports an electrothermal MEMS mirror-based LiDAR system. The MEMS mirror has a low driving voltage of 9 V and a large mirror aperture of 2 mm in diameter. The working range of this system is 80 to 250 cm with a distance resolution of 7.2 cm. The complete LiDAR prototype can fit into a small volume of 100 mm×100 mm×60 mm with the weight under 100 g. The use of such a MEMS mirror can greatly reduce the weight, size and power of LiDAR modules, making it possible for small UAVs to carry LiDAR for accurate navigation.
