Analysis of the pi phase-shifts obtained in the Fourier spectra of phase gratings and grids by using two-window grating interferometry
As it is very well known, the Fourier coefficients of only-phase gratings are Bessel functions of the first kind of integer order. Because the values of these real-valued functions oscillate around zero, they can adopt negative values, thereby producing phase shifts of π between some diffractio...
