Detection of Moving Objects and Laser Power Supply by Visible Laser Diode

Abstract

We investigated LiDAR using visible light laser diodes (LDs) and an optical power supply using visible laser diode (LD) are investigated. With LiDAR using a red LD, we obtained characteristics that ranged up to about 8 m, even with a 10% reflective blackboard, and about 3 times that with a 90% reflective white board. In addition, a laser power supply with a visible LD was achieved with more than 90% light transmission efficiency in both the red and the blue LDs. We also successfully demonstrated visible-laser feeding to a moving object that was detected by visible-light LiDAR.
