Abstract
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.
