Paper Abstract

We describe a laboratory experiment to improve the energy-on-target for an extended object. We utilize an iterative approach combining digital holography for detection and SLM beam shaping for object re-illumination. We developed a technique to modify the SLM phase to prevent oversharpening of glints and other high intensity return signal points that cause the beam to collapse to a single point with further iterations. Instead, the gain is increased as more light uniformly hits the intended target with each iteration. We present laboratory results to verify this approach and demonstrate the increased gain resulting from this dynamic beam-shaping.
