Fast generation of arbitrary optical focus array
Optics and Lasers in Engineering（2023）
Abstract
•A fast algorithm for arbitrary focus array generation is proposed.•Both the position and intensity of each focal spot can be controlled at high accuracy.•The focus array generation with uniform and nonuniform positions and intensities is demonstrated by both simulation and experiment.
