摘要：

All CCD-based photon-counting detectors using interpolative centroiding suffer from periodic pattern noise arising from errors associated with the centroiding algorithm. A new centroiding technique is described which removes this pattern noise. The use of a lookup table in hardware enables the pattern noise to be corrected in real time.
