T. Shibuya, M. Torii, K. Ukai, S. Komatsu and T. Mihashi: Effect of Defocus on Measurement of Wave Aberration in Human Eye Using 2-D Grating and Fourier Analysis, Extended Abstracts (Optics Japan 2005), 614-615.

Wave-front aberrations in human eye are generally evaluated by using Zernike polynomials. We have already reported the feasibility of the new measurement metod of wave-front aberration in human eye using 2-deimensional grating and Fourier analysis. In this study, we show that defocus (Zernike term 5) and other aberrations (other Zernike terms) can be treated separately by this method.
