Abstract
An analysis of the image fill factor effect on Zernike-type phase contrast filtering is presented. We define image fill factor as the ratio of the object support area over the illuminating area. Numerical simulations are presented for binary phase objects where the contrast of the output image is evaluated as a function of the image fill factor and image phase variations. The results obtained show that the image fill factor can significantly modify the contrast of the output image.
