Abstract :
An experimental thin-film CdS:CdSe photoconductordiode array having 80 × 12 elements has been fabricated by vacuum deposition on a single 4 × 8 inch substrate. Element spacing is the same as the hole positions in a standard computer punched card. Possible applications include static and dynamic card readers.
