<P>PROBLEM TO BE SOLVED: To provide a deformation method for obtaining a voltage template closest to an ideal voltage template and then deforming a deformable mirror based on the voltage template, and to provide an optical device and a fundus observation device using the same. <P>SOLUTION: The deformation method for a deformable mirror which corrects wavefront distortion of a luminous flux on a reflecting surface by deforming the reflecting surface of the deformable mirror including a plurality of electrodes to which a voltage is applied, and a thin film reflecting surface which is disposed opposing to the electrodes and which causes distortion by an electrostatic voltage applied on the electrodes. In the method, the light reflected by the deformable mirror from an object is detected, a predetermined number of groups of applied voltages corresponding to a predetermined different number of reflecting surface shapes are stored as one group of applied voltage onto the respective electrodes corresponding to one referential reflecting surface shape, a group of applied voltages suitable for an detection signal to be aimed is determined, the predetermined group of applied voltages corresponding to the reflecting surface shape is updated, and the deformable mirror is made to be deformed on the basis of the updated group. <P>COPYRIGHT: (C)2007,JPO&INPIT |
