ABSTRACT:
A method of transparency viewing, including, placing the transparency at a viewing surface, forming a light pattern and projecting the light pattern to back-illuminate the transparency. Preferably, the light pattern is formed by spatially modulating a beam of light using a plurality of light-valves.
