Patent ID: 8558207

Claim:
A photostimulable plate reading device, comprising; at least one photostimulable plate carrying image data and having two opposite surfaces; an illuminating device configured to homogeneously illuminate a first one of the two opposite surfaces of the at least one photostimulable plate with light emitted in a first wavelength range, the illumination causing the at least one photostimulable plate both to emit light in a second wavelength range by photostimulated luminescence and to scatter light in the first wavelength range; a filter device configured to prevent the light scattered in the first wavelength range from passing and for allowing the light emitted in the second wavelength range to pass, the filter device facing a second one of the two opposite surfaces of the at least one photostimulable plate; and a detector composed of a two dimensional array of pixels for detecting the light allowed to pass and for obtaining image data therefrom, wherein the filter device includes a block of optical fibers having two opposite surfaces and a thin multilayered filter bonded to a surface of the block of optical fibers facing the second one of the two opposite surfaces of the at least one photostimulable plate, the at least one photostimulable plate being bonded to the multi-layer filter, the thin multilayered filter including several superimposed layers each having a different refractive index.
