The dependence of the image quality of holographic real images on the reconstruction geometry

Abstract

The effect of changes in plate orientation on the resolution of holographic real images is studied experimentally. Resolution of 64 line pairs per mm was observed in the reconstructed real image from a hologram (NA 0.12, reconstruction beam angle 11 degrees ). Attainment of this performance required alignment of the plate to within 5 minutes of arc. Calculation of the aberration produced by a change in reference beam angle correlated with observed astigmatism and resolution.
