What will I learn?
Gain practical tools to analyze and design diffraction setups confidently. Review wave optics fundamentals, master Fresnel and Fraunhofer diffraction regimes, calculate Fresnel numbers, model slits and circular apertures, predict detector spot sizes and lobe widths, select optimal dimensions, and verify with numerical FFT simulations and easy experiments.
Elevify advantages
Develop skills
- Master diffraction regimes: quickly decide Fresnel vs Fraunhofer for any setup.
- Compute slit and Airy patterns: predict minima, lobe widths, and detector spots.
- Design apertures fast: size slits and holes to hit target sensor coverage at 0.5 m.
- Apply Fresnel number: judge approximation error and choose analytic or numeric tools.
- Simulate and validate beams: run FFT propagation and extract precise lobe metrics.
