“…Class-1 will be reached in the next generation by using an "eye safe" wavelength such as 1550nm infrared laser. 3 Due to the high current variation that occurs as a function of the voltage, a current regulation approach is needed to manage a stable optical power. One main feature of VCSEL, is the low commutation current close to 2mA that requires a fine tuning regulation setup.…”

The two approaches presented in this paper consist of splitting the tracking action into two sub-systems. The decoupling of local scanning and global scanning functions is an alternative solution to the use of fast-steering, power-consuming galvanometric scanner. Applications targeted are multi-object tracking and 3D perception in safe condition. This paper presents more specifically an approach based on a Risley prism configuration steering a laser pattern dynamically shaped by a DMD * allowing a good compromise for the refresh rate and the precision.
