Optical writing and erasing with bistable-phosphor storage tubes

Using the photoconductive property of the luminescent screen of bi-stable-phosphor storage tubes, optical writing can be accomplished by projecting an image onto the phosphor layer or exciting local areas with a light pen. A modification of the tube structure to permit selective erasure as well as w...

Description
Summary:Using the photoconductive property of the luminescent screen of bi-stable-phosphor storage tubes, optical writing can be accomplished by projecting an image onto the phosphor layer or exciting local areas with a light pen. A modification of the tube structure to permit selective erasure as well as writing by optical means is also discussed.
