Evaluating the efficient of imaging processes

This review describes the techniques which are used to evaluate the properties of the recorded image. These techniques are described from the viewpoints of Fourier analysis, quantum efficiency, and information theory. An analysis is made of the mechanisms of conventional silver halide processes which control their imaging efficiency and image quality. Some examples of the methods of image evaluation are given for practical problems involving X-ray images, electronographic cameras and image intensifiers in astronomy, and for the electrophotographic process.
