SIMPLE MEASURE FOR THE AMOUNT OF INFORMATION OF MEASUREMENT SYSTEMS

Measurement systems consisting of multiple measurements of an object a re considered and their linear dependency is gradually quantified. Dis turbances are taken into account by a simple model. The measurement op erator is described by its singular value decomposition allowing a dee per insight into its transfer characteristics. The meaning of the sing ular values is discussed and they are used to define a measure for the amount of information. The concept presented can be used as a simple tool for experimental design the usefulness of which is demonstrated b y applying it to a tomographic problem.
