Diffraction Course
This course builds expertise in diffraction from basics to practical sensor design applications. Explore Fresnel and Fraunhofer regimes, Airy disk patterns, slit diffraction models, and FFT propagation techniques to accurately predict spot sizes, optimize aperture dimensions, and confirm results through numerical simulations and real-world experiments.
