Patent ID: 7635186

Claim:
An ophthalmologic measuring apparatus comprising: a light source part to emit a high-intensity light flux at a specified timing; an illuminating optical system which includes a first polarizing optical member to alternately change a polarization condition to a first polarized light or a second polarized light and illuminates the light flux from the light source part to an ocular fundus of a subject eye through the first polarizing optical member; a light receiving optical system which includes a second polarizing optical member to select each polarized light component of reflected light from the subject eye illuminated according to the polarization condition of the first polarizing optical member and, a first and a second light receiving parts to alternately receive the reflected light through a first and a second conversion members each dividing the reflected light of the selected polarized light component into at least 17 light fluxes; and a measurement part which reads first measurement data from the second light receiving part while the first light receiving part is being exposed to light, and on the other hand, reads second measurement data from the first light receiving part while the second light receiving part is being exposed to light, writes the first measurement data and the second measurement data into a memory respectively, after a number of times of measurement has reached a predetermined value, reads the first and the second measurement data from the memory and, performs an analysis of a wavefront aberration of the subject eye based on read first and second measurement data of short intervals which is shorter than intervals of measurements by each of the first and second light receiving parts.
