Question
(a) For a one-dimensional periodic object illuminated by a uniform plane wave, find the location of the longitudinal self-imaging planes. [4](b) If the self-imaging planes are 1 cm apart, what is the transverse periodicity of the object? Assume the wavelength of illumination as 1 micron. [3]
(c) Also, find the locations of the planes where one can observe contrast reversal. [3 (a) For a one-dimensional periodic object illuminated by a uniform plane wave, find the location of the longitudinal self-imaging planes. [4]
