    • A device for acquiring information contained in a phosphor layer comprises a light source (2) for irradiating the phosphor layer (1) with excitation light (3) that is suitable for exciting emission light (4) in the phosphor layer (1), a detector (6) for detecting the emission light (4) that has been excited in the phosphor layer (1), and a filter device (8), arranged between the phosphor layer (1) and the detector (6), that is substantially transparent in a first wavelength range (W1) of the emission light (4) and substantially non-transparent in a second wavelength range (W2) of the excitation light (3). To increase the reliability during the acquisition of the emission light, the filter device (8) is made substantially non-transparent in at least a third wavelength range (W3) having longer wavelengths than the second wavelength range (W2) of the excitation light (3).

    • An X-Ray cassette (1) and a device (10) for reading information stored in a memory layer (15) are disclosed. This device (10) contains a radiation source (11) to excite a row (34) of the memory layer (15). The row (34) emits an emission radiation (17) because of this excitation. The device (10) based on the invention contains a receptor (12) to receive the emission radiation (17). The receptor (12) includes a number of light-sensitive surfaces (18) that are arranged in adjacent rows. According to the invention, the dimension of the light-sensitive surfaces (18) of the receptor (12) arranged perpendicular to the orientation (A) of the rows (34) is greater than that oriented along the row direction (B). Alternatively or additionally, the device can include an optical projector (14) by means of which the emission radiation (17) is projected onto the receptor (12). The numerical aperture of the optical projector (14) with respect to the excited row (34) arranged perpendicular to the orientation (A) of the rows (34) is larger than along direction (B).
