Abstract

A novel human eye aberration measurement method based on information fusion is presented here. We built a combined subjective and objective human eye aberration measurement system which is composed by an objective measurement part which measure human eye aberration by using Hartmann-Shack wavefront sensor and a subjective view test part through which can test the subject's vision. The deformable mirror can compensate the high order aberrations of human eye, and thus, can improve the visual acuity of human eye. We had weighting process on Zernike coefficients of both psychology stimulated results and objective results by the method of information fusion, and got combined Zernike coefficients, and finally the combined wavefront aberrations. The result shows that information fusion can combine advantages of both subjective and objective measurement, can have more comprehensive to characterized human eye visual performance, thus providing a more detailed advice for ideal individual human eye.
