| Popis: | Image photon counting systems are limited in dynamic range by clumping of photon events which cannot be disentangled by the reduction processing. The loss of linearity is studied for overlapping of photon events of the same diameter. More realistic situations taking into account the pulse width distribution of the events and the limitations of the processing systems are also examined. In all cases, the dynamic range of image counting systems is limited to low counting rates. These systems require high resolution intensifiers and fast readouts of the target of the pickup tube. |
