| Abstract: | Based on the Extended Nijboer-Zernike theory,the effect of different amplitudes for exit pupils on the image intensity in the focal plane was analyzed.A novel approach was applied to testing the wavefront according to the actual condition of the amplitude in the exit pupil,which can help eliminating the error caused by the nonuniformity illuminated pupil and the Fast Fourier Transform in the original phase retrieval algorithms.A testing experiment was performed on an imaging optical system,and obtained resu... |
