Chapter 15: Coherence Theory Solution to the Pinhole Camera
To illustrate some of the techniques used in solving propagation problems, the formalism of coherence theory developed in Chapters 10 and 11 is applied to a simple image formation system - a pinhole camera. Theoretical predictions are compared with typical experimental results. As discussed in Chapter 11, the quantity of interest in coherence theory is a cross-correlation function between the complex amplitude of the optical field at two separate space-time points. For many problems (including those of image formation) in which polarization effects are not important, the optical field can be treated as a scalar quantity.
