    The Fourier Optics module focuses on applying Fourier analysis to understand and design optical systems. Students will learn to describe optical signals as superpositions of tilted plane waves and define linear and shift-invariant (LSI) optical systems. The module emphasizes identifying criteria for determining if an optical system is LSI and exploring the mathematical implications. Key concepts include expressing the output of LSI systems as convolutions of input signals with impulse responses, facilitating system analysis. We will estimate the complex amplitude distribution in free propagation under Fresnel and Fraunhofer regimes. Additionally, students will explore image processing in the Fourier domain, gaining skills to analyze, filter, and manipulate images. This module bridges optics, mathematics, and image processing techniques.

    This Module has 4 classes.
