Definitions for "Photomultiplier tube"
Drum scanners use photomultiplier tubes to receive color and value information about an image. Photomultiplier tubes do not produce the undesired effects that charged coupled devices create.
A color-sensing device used in high-end DRUM SCANNERS. Like CCD s, photomultiplier tubes convert light into electrical impulses which can be interpreted by a computer. PMTs, however, are much more sensitive than CCDs, and offer much grater resolution and detail-resolving ability.
A device for amplifying the flashes of light produced by a scintillator.
