Linear Phase Conjugation for Atmospheric Aberration Compensation
نویسندگان
چکیده
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 Grumman’s aberration compensation technique results in a high fidelity, near-diffraction limited laser beam delivered to the target.

Compensation of distant phase-distorting layers. I. Narrow-field-of-view adaptive receiver system.
We analyze various scenarios of adaptive wave-front phase-aberration correction in optical-receiver-type systems when inhomogeneties of the wave propagation medium are either distributed along the propagation path or localized in a few thin layers remotely located from the receiver telescope pupil. Phase-aberration compensation is performed with closed-loop control architectures based on decoup...

The ability of nonlinear optical phase-conjugate mirrors (PCM's) to correct for linear refractive-index inhomogeneities has been demonstrated both theoretically1'2 and experimentally.2 Propagation media often possess intensity-dependent indices of refraction that cause severe propagation distortion, such as thermal blooming and self-focusing. These distortions are often manifested in high-inten...

Optical aberrations that are due to high-speed turbulence in the aero-optical regime are corrected with optical phase conjugation based on coherent population trapping in sodium vapor. Experimental measurements of an unheated, forced helium jet in air have demonstrated aberration correction by a factor of 7.8 at a forcing frequency of 18kHz with an optical power gain of 32.
متن کاملPhase plates for wave-aberration compensation in the human eye.
We present a method for manufacturing phase plates to compensate for the wave aberration in the human eye. The wave aberration of the eye is measured in vivo by a new laser ray-tracing method and then compensated for by a phase plate placed in front of the eye. This plate is made from a gray-level single-mask photosculpture in photoresist. Two experiments were carried out, first with an artific...
