Abstract
An image recording and readout device has a light-stimulable phosphor layer for storing a radiation image. The image is read out of the phosphor layer by scanning the layer with a laser beam. A filter is provided between the phosphor layer and the laser to increase the coupling of the laser light into the phosphor layer. The filter passes stimulating laser radiation within an angular acceptance range and reflects stimulating radiation outside the acceptance range.
