Abstract

We propose a method for 2D multiple beam generation without causing extraneous beams in the ASTRO architecture. By simply adding a circular light block (spatial filter) at the center of the polygon mirror on the ASTRO true time delay generator, all the extraneous beams can be removed without requiring additional hardware. Experimental results to prove the concepts will be described with related analyses.
