Abstract:
1. A radiation readout apparatus comprising: a concave mirror defining a central optical axis; a refractive lens assembly spaced from said concave mirror and symmetrical with said optical axis; an optical assembly which is optically coupled to said refractive lens assembly and to a stimulable phosphor location on one side of said optical axis and to a linear sensor location on the other side of said optical axis; a stimulating radiation beam delivery system including a stimulating radiation beam source for producing a stimulating radiation beam of a first wavelength and beam shaping elements; a color filter, located at said linear sensor location, for filtering out leaked stimulating radiation; and a dichroic prism optically coupled to said optical assembly for directing a linear stimulating radiation beam of said first wavelength from said stimulating radiation beam delivery system, which is projected into said dichroic prism, to a stimulable phosphor at said stimulable phosphor location, wherein stimulated radiation of a second wavelength emitted by said stimulable phosphor is passed back through said dichroic prism through said optical assembly, through said refractive lens assembly, reflected from said concave mirror, passed back through said refractive lens assembly, through said optical assembly, through said color filter, and to a linear sensor located at said sensor location.
