Aplane wave of wavelength 1 is used to construct a hologram. a beam splitter is selected that makes the amplitude of the reference beam n-times that of the signal beam at the emulsion. the emulsion has refractive index of n. the directions of the reference and the signal beams are 0-degrees apart. during processing, the emulsion shrinks by a percentage p%.
a) what is the visibility of the hologram determined to 4-decimal places
b) what is the spacing of the fringes of the hologram after processing.
