Motion control of the wedge prisms in Risley-prism-based beam steering system for precise target tracking.

Abstract

Two exact inverse solutions of Risley prisms have been given by previous authors, based on which we calculate the gradients of the scan field that open a way to investigate the nonlinear relationship between the slewing rate of the beam and the required angular velocities of the two wedge prisms in the Risley-prism-based beam steering system for target… (More)
