Polarization effects in holography.

Abstract : Holograms were made of the reflected beam from a simple object which had its angle of polarization varied from parallel to orthogonal in relation to the polarization in the reference beam. The brightness of the light diffracted into the image by the hologram was measured with a Spectra-Pritchard photometer. The results are presented in graphical form. It was concluded that polarization phase angles should not exceed about fifteen degrees when calculating the beam ratios for holograms. (Author)
