Magneto-Optic Pattern Generators for Electrophotographic Printers

摘要

The magneto-optic light switching technique and its feasibility for electronic reproduction of text or graphics by electrophotography were studied. An optical line-pattern generator to be used as electro-optic input device was constructed. Based on magneto-optic switching arrays, the best matching of spectral features, light output power and other essential parameters with the electrophotographic process was investigated. The results of recording experiments with an optimized design of light source, imaging optics and light switching array used to expose organic photo-conductors in a special electrophotographic test apparatus show the feasibility of the technique at medium recording speed.
