Journal ArticleDOI
TL;DR: In this method, halftone screened images are sampled twice with different sampling rates, and the selection of proper frequency components less suffering from aliasing errors can effectively suppress moire fringes.

Journal ArticleDOI
TL;DR: In this paper, the authors discussed the necessary number of sampling steps to reduce under-sampling errors in a fringe scanning interferometer and some examples of the necessary sampling steps.

Journal ArticleDOI
TL;DR: In this paper, the null test of an aspherical mirror from a spherical mirror was proposed without using any special optical element, where the excess optical path difference due to an off-axis scatter point was removed.

Journal ArticleDOI
TL;DR: In this article, the third and fifth-order wavelength shift aberrations for an off-axis holographic zone plate for the higher orders were discussed, and numerical calculations of the aberratures were presented.
Abstract: The third- and fifth-order wavelength-shift aberrations for an off-axis holographic zone plate for the higher orders are discussed, and numerical calculations of the aberrations are presented. A stigmatic point image can be obtained in the nth diffracted order if the wavelength-shift ratio is equal to 1/n.
