Signal Amplification By Charging And Illuminating A Partially Developed Latent Electrostatic Image
US Patent:
4038943, Aug 2, 1977
Filed:
Jun 20, 1975
Appl. No.:
5/588573
Inventors:
Alan C. Nelson - Los Angeles CA
Lothar S. Jeromin - Sierra Madre CA
Lothar S. Jeromin - Sierra Madre CA
Assignee:
Xerox Corporation - Stamford CT
International Classification:
G03G 1508
US Classification:
118647
Abstract:
Method and apparatus for reducing X-ray dosage required for xeroradiographic examinations without reducing the relative information capacity of the images produced during the examination. In particular, a charged xerographic plate is positioned adjacent the object to be examined and penetrating X-ray radiation is projected through the object onto the plate surface, forming a latent electrostatic image on the surface of the plate. The penetrating radiation utilized is of a substantially lower dosage than normally utilized. The image is then partially developed with developing powder and the partially developed image is then charged and exposed to substantially uniform radiation. The exposed charged image is finally developed by applying additional developing powder thereto resulting in an enhanced image or signal.
