英文摘要	As a criterion used to describe the performance of an optical system, optical transfer function (OTF) can be calculated by autocorrelation of pupil function, dual Fourier transform, Zernike polynomial fitting, and so on. A fast OTF calculation method based on dual Fourier transform and graphics processing unit (GPU), in which the redundant computations of point spread function (PSF) and OTF are removed, is proposed in this paper. For an optical system with the pupil function of 512 9 512 pixels, the OTF computation is implemented on GPU platform. The result shows that the proposed method using the 128 9 128 pixels central regions of the PSF enhances the computational efficiency of about 4.88 times than the method using standard CUFFT.
