TL;DR: In this article, a defocused optical field with a Ronchi grating was used to get a quasi-sine optical field and by using a grating ii phase shifting technique, the fundamental spectrum modulated by the object height distribution was theoretically extended from 0 to 2f0 (f0 is the carrier frequency of the optical field) without overlapping the zero component and other higher spectra.
