Selection of Photochromic Materials for Projective Displays

Stephen Herman

Photochromic materials can be used as erasable and reusable memories for projective displays. Measurements of the properties of available photochromic materials were made and the most sensitive optically-erasable and heat-erasable photochromics were subjected to further tests. Quantitative data were compiled for the most sensitive materials on exposure sensitivity, fatigue and information storage during projection. The heat-erasable material was found to be far superior for the general display application. It was more sensitive in exposure, less subject to fatigue and the image did not fade due to the visible projector illumination.
