ABERRATION COMPENSATION DEVICE, OPTICAL DEVICE, AND OBSERVATION DEVICE FOR OCULAR FUNDUS

摘要

PROBLEM TO BE SOLVED: To provide an aberration compensation device which enables calibration of a Zernike voltage template in accordance with the working environment and the manufacturing error of an individual deformable mirror.

SOLUTION: The aberration compensation device is equipped with the deformable mirror which has the a reflection face generating distortion by an electrostatic voltage applied to a plurality of electrode parts, measures the voltage applied to each electrode part when a desired shape of the reflection face is formed by detecting reflection from 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 the different shapes of the reflection face in advance, and deforms the reflection face into the desired shape by superposing the stored sets of the electrode part and the applied voltage. The aberration compensation device is equipped with an offset computing means which compares a stored detecting signal to the detecting signal actually detected to output the desired detecting signal by offsetting the stored detecting signal based on humidity and the condition of the use environment such as the manufacturing error.
