One of the methods for observing phase (transparent) objects is as follows: in the common focal plane of lenses L1 and L2, a transparent plate P is installed on the optical axis, introducing a phase delay of n/2 (figure). Find the intensity distribution I(x) in the image plane (in the rear focal plane of lens L2), if the object - a phase sinusoidal grating with an amplitude transmittance coefficient m(x) = exp(imcosWx), m 1 - is located in the front focal plane of lens L1.
