Abstract
A System and Method for Joint Compensation of Turbulence-induced-aberration and Laser Source Aberrations to provide measurement and compensation of aberrations in a laser beam projected from a laser source and the aberrations induced by propagation through an optical system and through a turbulent medium to a target utilizing only a single primary phase correction device means in the projected laser beam path and a secondary phase correction device means incorporated into the wavefront sensor path while at the same time the corrections are made using strictly null-seeking feedback control loops, thus providing a robust means of compensation. Reduction of the number of phase correction device means in the projected laser beam path can reduce cost, size, weight, and power compensation of the compensation system when the projected laser beam is a high energy laser.
