    • A method and to a corresponding apparatus reads out X-ray information stored in a storage phosphor plate (1), the storage phosphor plate (1) being irradiated with stimulation light (3) and so being stimulated into emitting emission light which is collected by a detector (9) during several measuring times and being converted into corresponding emission light signals (S, R). In order to guarantee high reliability when examining sensitivity fluctuations, in particular with different types of detectors, provision is made such that reference measurements are taken by the detector (9) during several reference measuring times and several reference signals are thus produced, the individual reference measuring times falling respectively between the measuring times, and the reference signals being used for examining the sensitivity of the detector (9) to emission light.

    • A process, and to a corresponding apparatus for reading out and erasing X-ray information stored in storage phosphor layers, comprising the following: irradiating the storage phosphor layer (1) with stimulation light (3) by means of which the storage phosphor layer (1) is stimulated to emit emission light, collecting the emission light emitted at different locations (x, y) of the storage phosphor layer (1) with a detector (7), detector signal values (D(x, y)) being obtained for different locations (x, y) of the storage phosphor layer (1), and irradiating the storage phosphor layer (1) with erasing light (21), the quantity of erasing light (21) being determined by means of the detector signal values (D(x, y)). When determining the quantity of erasing light (21), which is on the one hand sufficiently great in order to guarantee total erasure of the storage phosphor layer (1), and on the other hand is as low as possible, in order to avoid an unnecessarily high degree of heat development and to guarantee a high throughput, detector signal values (D(x, y)) obtained for different locations (x, y) in a first and second dimension (x or y) of the storage phosphor layer (1) are compared with comparison signal values (H(x), H′(x)) specified for different locations (x) in just one dimension (x) of the storage phosphor layer (1).

    • In a method for electronic image rectification in pixel-by-pixel scanning of a substrate by a bundled electromagnetic beam, the pixels are read out one after the other in readout intervals of constant predetermined duration. In order to improve image quality, the deviation between a reference scanning movement and an actual scanning movement carried out on the reference substrate is initially determined in a calibration process, for example, by a reference substrate with a known geometric surface structure. Depending on this deviation, a delay interval is determined for a pixel and the start of the readout interval of this pixel or of the subsequent pixel is delayed by this delay interval. The information about the delay interval is stored. In an analysis process for examining a substrate, the stored information about the delay interval is accessed for the pixel, and the delay interval is added before or after the readout interval.
    • 在通过捆扎电磁波束对基板进行像素像素扫描的电子图像整流方法中,像素以恒定的预定持续时间的读出间隔一个接一个读出。 为了提高图像质量,参考扫描运动和在参考基板上执行的实际扫描运动之间的偏差最初在校准过程中确定,例如通过具有已知几何表面结构的参考基板。 根据该偏差,确定像素的延迟间隔,并且该像素或后续像素的读出间隔的开始被延迟该延迟间隔。 存储有关延迟时间间隔的信息。 在用于检查基板的分析处理中,存储关于像素的关于延迟间隔的存储信息,并且在读出间隔之前或之后添加延迟间隔。
