Radiation image information read apparatus

摘要: In a radiation image information read apparatus, stimulable phosphor sheet, on which has been stored, is scanned with stimulating rays, and light emitted by the sheet upon stimulation thereof photoelectrically detected photodetector converted into an electric signal bearing thereon information. A solid laser crystal emits beam having wavelength of λ2 pumped at λ1 from diode combined nonlinear optical converts to λ3 within range employed as source light. filter cuts transmits disposed between photodetector. There are lens focuses predetermined position, aperture plate in position permits most pass therethrough while cutting λ1.
