James C. Wyant,V. P. Bennett +1 more
TL;DR: In this article, the use of computer generated holograms for the testing of aspheric wavefronts is described, and an analysis of the errors produced by emulsion movement, incorrect hologram size and position, and distortion in hologram plotter and photoreduction lens is given, and it is shown that all the errors are proportional to the slope of the wavefront.
