"Reflectance Paper" Can Reflect Light Like Physical Object
Added Aug 13, 2012 | Rate View top rated
A novel printing method yields photos that respond to different angles of light the same way a three-dimensional object does. The technique, which uses specially designed "reflectance paper" covered with thousands of tiny dimples, was developed by a team of researchers at the University of California, Santa Cruz, Hewlett-Packard Laboratories, and 3M. "With the reflectance paper, for each pixel we have a little dimple that has all angular directions on its surface. Now we can print ink over it in a way that controls the angles of light that will be reflected from each pixel," explains James Davis, an associate professor of computer science at UCSC.
