). Your solution must account for the four resulting terms: the bias, the two conjugate images (real and virtual), and the self-interference term. Tips for Success
If you are working through the , this guide breaks down the core concepts you need to master to solve them effectively. 1. Linear Systems and Scalar Diffraction (Chapters 2 & 3) When solving these
Remember that film or sensors record intensity ( When solving these
To find the OTF, you usually need to perform an autocorrelation of the pupil function. 5. Holography and Wavefront Reconstruction (Chapter 9) When solving these
Use properties like circular symmetry to convert 2D integrals into 1D Hankel Transforms (using Bessel functions). This is often the "shortcut" intended by the author.
You’ll often be asked to find the field distribution at a distance from an aperture.
When solving these, ensure you account for the "zero-padding" required to prevent circular convolution artifacts when simulating diffraction.
