Abstract:

The microreduction and enlargement of high-resolution graphic data such as map separations was investigated. Original graphics were photoreduced to 70 mm film transparencies and stored as 20 x 20 mm phase-randomized Fourier-transform holograms. Experimental data show that enlargement to full size produces only minimal distortion. Image brightness and brightness uniformity were adequate for reproduction. However, resolution and line quality did not meet current standards for cartographic production. Holography is judged to be a promising approach to high-density microstorage only if several fundamental problems can be solved. Author
