摘要
Method and apparatus for intensification and reflective read- out of underexposed films, radiographs, and the like are shown which include means for converting a metallic silver particle image to a highly reflective image. The film containing the highly reflective image is placed in a black-walled cavity which may contain a particle-free liquid, such as water. The image is raster scanned by a laser beam, and light reflected from the image is detected by a photomultiplier. The photomultiplier output is digitized and the digitized signal is stored for subsequent computer enhancement and display.
