To Fourier Optics Third Edition Problem Solutions - Introduction

Are you working on a or a particular problem number from Goodman's text that I can help clarify?

). In Fourier optics, these are typically in cycles per millimeter.

To find the OTF, you usually need to perform an autocorrelation of the pupil function. 5. Holography and Wavefront Reconstruction (Chapter 9) Are you working on a or a particular

The 3rd edition places a significant emphasis on numerical methods.

You’ll often be asked to find the field distribution at a distance from an aperture. To find the OTF, you usually need to

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.

is very large, the field is simply the Fourier transform of the input scaled by You’ll often be asked to find the field

Most early problems focus on the and its application to light propagation.
