Use Python (via NumPy and SciPy) or MATLAB to run a Fast Fourier Transform (FFT) on the aperture geometry described in the problem. Comparing your handwritten analytical equation against a quick numerical simulation plot is the fastest way to catch missing coefficients or sign errors.
Deriving the Optical Transfer Function (OTF) and Modulation Transfer Function (MTF).
: Understanding the 2D Fourier transform is crucial for analyzing image formation. Key theorems, such as the Similarity Theorem , relate spatial scaling to inverse scaling in the frequency domain. Use Python (via NumPy and SciPy) or MATLAB
Comprehensive problem solutions for Joseph W. Goodman's Introduction to Fourier Optics
Avoid generic online “solution manuals” – they are often for earlier editions, contain critical sign errors in the Fresnel integrals, or omit the all-important step of justifying the paraxial approximation. : Understanding the 2D Fourier transform is crucial
