<P>PROBLEM TO BE SOLVED: To provide an apparatus which is inexpensive since the wave front aberration of an eyeball is accurately measured without using a filter having a sinosoidal concentration distribution and requiring much time for measurement with a simple structure. <P>SOLUTION: In a refractive power distribution measuring apparatus, measurement light reflected from an eye ground is guided through a digital micromirror device having a plurality of micromirrors lengthwise and crosswise and reflecting light from the eye ground of an eye to be examined in two different directions to imaging means arranged in the two reflection directions, and the refractive power distribution of the eye to be examined is obtained from image data imaged by the imaging means. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
