Diffraction Course
This course builds expertise in diffraction from basic principles 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, optimise aperture dimensions, and confirm optical configurations through simulations and real-world tests.

What will I learn?
Gain practical skills to analyse and design aperture setups confidently. Review wave optics fundamentals, grasp Fresnel and Fraunhofer diffraction regimes, and calculate Fresnel numbers. Model slits and circular apertures, forecast central lobe widths on detectors, select optimal dimensions, and verify with numerical simulations and simple experiments.
Elevify advantages
Develop skills
- Master diffraction regimes: swiftly determine Fresnel versus Fraunhofer for any configuration.
- Calculate slit and Airy patterns: forecast minima positions, lobe widths, and detector spot sizes.
- Design apertures efficiently: dimension slits and apertures for precise sensor coverage at 0.5 m distance.
- Utilise Fresnel number effectively: assess approximation accuracy and select analytical or numerical methods.
- Simulate and verify beam propagation: perform FFT simulations and measure exact lobe characteristics.
