Many solutions require you to determine the minimum sampling rate to avoid aliasing.
). In Fourier optics, these are typically in cycles per millimeter. Many solutions require you to determine the minimum
When solving these, ensure you account for the "zero-padding" required to prevent circular convolution artifacts when simulating diffraction. When solving these, ensure you account for the
The 3rd edition places a significant emphasis on numerical methods. If the problem involves large distances, the Fraunhofer
Mastering the Fundamentals: Introduction to Fourier Optics, 3rd Edition Problem Solutions
Practice switching between the spatial domain (using convolutions) and the frequency domain (using transfer functions). If the problem involves large distances, the Fraunhofer approximation simplifies the solution to a direct Fourier Transform of the aperture. 2. Fresnel and Fraunhofer Diffraction (Chapter 4) This is where many students struggle with the math.
). 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
