Programmable light modulator for viewing transparent film prints

摘要

An improved apparatus for viewing transparent film prints, such as X-rays, mammograms and sonograms, is provided, which apparatus includes a light source, a viewing stage and an array of light valves to selectively prevent the transmission of light from the light source to certain areas of the viewing stage. The apparatus allows an operator to more efficiently and accurately discern detail in the analysis of transparent film prints.
