Chapter 7:
Image Formation: The Transfer Function
Editor(s): George O. Reynolds; John B. DeVelis; George B. Parrent; Brian J. Thompson
Until now we have considered image formation in terms of convolution of the intensity impulse response (intensity diffraction pattern) with the intensity distribution of an incoherently illuminated object. This approach to image formation, while correct and frequently useful, is often difficult to apply. An alternative approach, which simplifies the solution of many problems and is well suited for complicated objects, is the transfer function analysis. We will develop this analysis by means of an example. To minimize mathematical complexities, we have limited the analysis to one dimension.
