Diffraction Course
This course builds expertise in diffraction principles essential for optical sensor design. Participants explore wave optics fundamentals, Fresnel and Fraunhofer diffraction regimes, Airy disk patterns, slit diffraction models, and FFT-based beam propagation techniques. Learners gain skills to accurately predict spot sizes on detectors, select optimal aperture dimensions for specific distances like 0.5 meters, assess approximation errors using Fresnel numbers, and confirm predictions through numerical simulations and simple experiments, enabling confident analysis and design of diffraction-limited optical systems in practical applications.

What will I learn?
Gain practical expertise in diffraction analysis and aperture design. Review essential wave optics, master Fresnel and Fraunhofer diffraction regimes, calculate Fresnel numbers for regime selection, model diffraction from slits and circular apertures, predict central lobe widths and spot sizes on detectors, determine optimal dimensions for target coverage at distances such as 0.5 m, and verify theoretical predictions with numerical simulations like FFT propagation and accessible hands-on experiments.
