1 December 1991 CAD system for CGHs and laser beam lithography
Author Affiliations +
An interactive CAD system for a computer-generated hologram (CGH) is developed to produce many kinds of CGHs in the form of Postscript files, G-code files for NC machines, and HPGL files. These files can later be sent to a laser printer and also a laser beam lithography system. The laser beam lithography system developed has a writing area of 200 mmA approximately 200 mm with 0.5E m positional accuracy. By using the LBL system, some CGHs for optical interconnection and kinoforms are optimized with the simulated annealing algorithm.
