  • Supported or self-supporting photo stimulable phosphor panel comprising a volume reflection hologram
    Patent number: 5523584
    Abstract: A combination is provided comprising a supported or self supporting photostimulable phosphor panel, comprising a photostimulable phosphor layer, the phosphor being capable of storing energy upon irradiation with X-rays and of releasing the stored energy as stimulated emission light upon irradiation with stimulating light and collecting means for stimulated emission light, and showing a restricted angular aperture. The combination comprises a volume reflection hologram H1, situated between the phosphor panel and the light collecting means. The volume reflection hologram H1 reflects stimulated emission light entering the volume reflection hologram under any angle outside a restricted angle, determined by the angular aperture of the collecting means and transmits stimulated emission light entering the volume reflection hologram under the predetermined restricted angle.
