EYEGROUND OBSERVATION DEVICE AND EYEGROUND OBSERVATION METHOD

摘要

It is possible to improve the quality of an image of an eyeground, thereby acquiring an optimal image. An eyeground observation system (3) acquires an eyeground image via a compensation optical section (70) correcting the image of the eyeground obtained by illumination of an eyeground illumination system (2). A wave front correction system (1) measures wave front measurement data including a wave front aberration of the eye to be checked and/or aberration to be corrected, thereby acquiring the optical characteristic of the eye to be checked. An image data formation section (14-2) performs simulation of viewing at the eyeground, thereby calculating the simulation image data or MTF data. A correction amount decision section (14-3) decides a correction amount according to a voltage change template stored in a memory (14-4) and outputs it to a control section (15). Moreover, the correction amount decision section (14-3) uses the simulation result for a plurality of voltage change templates so as to calculate a value indicating the matching degree of the pattern or MTF data corresponding to a spatial frequency of cells of the eyeground and decide an appropriate correction amount.
