Adaptive piston correction of sparse aperture systems with stochastic parallel gradient descent algorithm
A phased sparse aperture system provides an economic solution to get high resolution images with less volume and weight. The crucial point of such systems is adaptive correction of piston, that is, a close-loop control aiming at stabilizing the optical path differences within a fraction of the wavel...
