Diffraction Course
This course builds expertise in diffraction from basics to practical sensor design. Explore Fresnel and Fraunhofer regimes, Airy patterns, slit diffraction models, and FFT propagation techniques to forecast spot sizes, optimise apertures, and confirm optical systems through real-world physics applications and validations.

What will I learn?
Gain practical skills to analyse and design aperture setups confidently. Review wave optics fundamentals, grasp Fresnel and Fraunhofer diffraction 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 choose Fresnel or Fraunhofer for any configuration.
- Calculate slit and Airy patterns: forecast minima, lobe widths, and detector footprints.
- Design apertures efficiently: dimension slits and openings for precise sensor coverage at 0.5 m.
- Utilise Fresnel number: assess approximation accuracy and select analytic or numerical methods.
- Simulate and confirm beams: perform FFT propagation and measure exact lobe parameters.
