Diffraction Course
This course delivers a thorough understanding of diffraction, progressing from core wave optics to practical sensor design applications. Participants will grasp Fresnel and Fraunhofer regimes, master Airy patterns and slit diffraction models, and apply FFT-based propagation techniques to accurately predict spot sizes, optimise aperture choices, and verify optical systems using real-world physics validations.
