Patent ID: 8022344

Claim:
An optical wavefront control pattern generating apparatus which generates an optimum optical wavefront control pattern which is to be stored in an optical wavefront controller unit, in an image reconstruction system displaying a reconstructed image of an object on a reconstructed image display unit, by irradiating the optical wavefront controller unit, in which an optical wavefront control pattern is recorded, with illuminating light, the apparatus comprising: a target image detector unit configured to detect spatial information of the object as a target image; a reconstructed image detector unit configured to detect the reconstructed image displayed by the reconstructed image display unit; and an optimizer unit configured to evaluate, on the basis of the target image detected by the target image detector unit, the reconstructed image detected by the reconstructed image detector unit, and to apply a modification process to the optical wavefront control pattern to satisfy a predetermined condition, so as to generate the optimum optical wavefront control pattern, wherein the optimizer unit is configured to generate the optimum optical wavefront control pattern, by repeating application of a modification process to an optical wavefront control pattern, computation of an evaluation value of a reconstructed image of the optical wavefront control pattern to which the modification process has been applied, and determination, on the basis of the evaluation value, of whether or not the optical wavefront control pattern, to which the modification process has been applied, is to be adopted; on the basis of difference information on evaluation values of reconstructed images respectively before and after the modification process, the optimizer unit is configured to determine whether or not the optical wavefront control pattern, to which the modification process has been applied, is to be adopted; and on the basis of the difference information and an adoption probability determined by a repetitive parameter value, the optimizer unit is configured to determine whether or not the optical wavefront control pattern, to which the modification process has been applied, is to be adopted.
