Analysis of the π phase-shifts obtained in the Fourier spectra of phase gratings and grids by using two-window grating interferometry
Fuente:

Resumen: 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 diffr...
