Diffraction Course
Master diffraction principles from basics to practical sensor design applications. Explore Fresnel and Fraunhofer regimes, Airy patterns, slit diffraction models, and FFT propagation techniques to accurately predict spot sizes, optimise aperture choices, and validate optical systems using real-world physics experiments and numerical methods.

4 to 360 hours flexible workload

What will I learn?
Gain practical skills to analyse and design aperture setups confidently. Review wave optics fundamentals, grasp Fresnel and Fraunhofer regimes, calculate Fresnel numbers, model slits and circular apertures, predict central lobe widths on detectors, select optimal dimensions, and verify with 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, lobe widths, and detector spot sizes.
- Design apertures efficiently: dimension slits and apertures for precise sensor coverage at 0.5 metres.
- Utilise Fresnel number effectively: assess approximation accuracy and select analytic or numerical approaches.
- Simulate and verify beam propagation: perform FFT simulations and measure exact lobe characteristics.
