Computer Generated Hologram Construction Kit
As an alternative to the photochemistry and vibration-free settings involved with regular holography, this program allows you to create a transmission hologram using just a computer, a laser printer, and an overhead transparency. This hologram will behave like one created using a laser, and can be projected or viewed with a point source. You create a computer-generated hologram using the MedCosm CGHMaker by specifying an input file as either a GIF image, a JAVA program, or an XML "point-source" list. Compute the interference fringes, print on a transparency, and enjoy your hologram.

Release Notes: The "randomize phase" feature was fixed so that it now works correctly. This feature assigns random phases to all points in the object in order to kill any structure that results from starting off with all object-point phases identical. This should produce better quality reconstructed images, though experiments are needed to be sure. The Java Web-Start was also fixed so that the latest version of the program can be run straight from a Web browser.

Release Notes: Minor feature enhancements were done to make experimenting a bit easier. These changes include output window labelling, reorganized output algorithms, new intensity output, threshold available for all binary outputs, a median/50% threshold button, display output byte clipping, and normalized output options.
