Diffraction Course
This course builds expertise in diffraction from basic principles to practical sensor design applications. Participants will master Fresnel and Fraunhofer regimes, Airy disk patterns, slit diffraction models, and FFT-based beam propagation techniques. Learners will accurately predict spot sizes, select appropriate apertures, and validate optical setups using real-world physics simulations and experiments, ensuring reliable performance at distances like 0.5 meters.
