Abstract

A reconfigurable lens, which is a tandem of a physical lens and a two-dimensional liquid crystal phase modulator, is controlled by an electro-optical system to correct degraded imaging properties. A computer iteratively changes a phase distribution of the modulator and evaluates an image to optimize the phase distribution, based on the simulated annealing algorithm. We demonstrate correction of imaging properties degraded by defocusing or phase objects inserted into an imaging system. The corrected imaging properties are even better than the original ones.
