Northrop Grumman reports on a program utilizing Linear Phase Conjugation to compensate for atmospheric induced aberrations that severely limit laser performance. In a program to improve both the beam quality and laser energy delivered to the target, Northrop Grumman has developed a novel aberration compensation technique. This technique, hereafter referred to as Active Tracking System, utilizes a silicon Spatial Light Modulator as a dynamic wavefront reversing element to undo aberrations induced by the atmosphere, platform motion, or both. Northrop Grummans aberration compensation technique results in a high fidelity, near-diffraction limited laser beam delivered to the target.
