QUICK IMAGE CORRECTION FOR A SIMPLIFIED ADAPTIVE OPTICS

摘要

A computer-aided image correction method for images with at least spatially partially coherent light requiring only a phase-modulated image as input. It does not reconstruct the phases on the image sensor, but rather assumes that they should ideally all be the same. With this assumption, the invention formulates a constraint and an update rule. The result of the iteration is an amplitude distribution of the lightwave field, which could have been measured directly if aberrations in the form of wavefront distortions had not contributed to the actual image acquisition. Further, a device that can, using the image correction method, be used as an adaptive optic for imaging instruments.
