METHOD OF DEFORMING DEFORMABLE MIRROR, OPTICAL DEVICE, AND OBSERVATION DEVICE FOR OCULAR FUNDUS

摘要

PPROBLEM TO BE SOLVED: To compensate aberrations of an optical device including an observation device for ocular fundus by using a deformable mirror offsetting wavefront distortion of a luminous flux of a reflection face. PSOLUTION: The deformable mirror is equipped with a plurality of electrode parts and the thin film-shaped reflection face which is disposed counter to the electrodes and generates distortion by an electrostatic voltage applied to the electrode parts, measures the voltage applied to each electrode part when a desired shape of the reflection face is formed by detecting reflection of the reflection face, takes the applied voltage to each electrode part corresponding to the reference shape of the reflection face as one set to store the prescribed number of sets corresponding to the prescribed number of different shapes of the reflection face, deforms the reflection face into the desired shape by superposing the stored sets of the electrode part and the applied voltage, and compensates the aberration. Preferably, the reference shape of the reflection face is stored in relation to a prescribed dimensionality of Zernike polynomials. PCOPYRIGHT: (C)2007,JPO&INPIT
