Optical-characteristic measurement apparatus and fundus-image observation apparatus |
摘要 |
An eye-anterior-part observation system receives light reflected from an eye anterior part of the eye under measurement illuminated by an eye-anterior-part illumination light source. A movement-distance calculation section measures the displacement of the eye from an eye anterior image by the eye-anterior-part observation system. A wavefront compensation device compensates the wavefront of light reflected or transmitted. A wavefront-measurement section projects light on the eyeground, and receives light reflected from the eyeground through the wavefront compensation device. A calculation apparatus measures wavefront aberrations, based on the measured displacement of the eye and a light-receiving signal by the wavefront-measurement section. A wavefront-compensation-device control apparatus generates a control signal based on the wavefront aberration, and outputs to the wavefront compensation device to compensate the wavefront. A stage with a motor moves the wavefront compensation device in a direction transversing the optical axis of the reflected light, based on the displacement of the eye.
