What will I learn?
Gain hands-on skills to analyse and design aperture systems confidently. Master wave optics fundamentals, Fresnel and Fraunhofer diffraction regimes, and Fresnel number calculations. Model slits and circular apertures, forecast central lobe widths on detectors, select optimal sizes, and confirm findings with simulations and simple experiments.
Elevify advantages
Develop skills
- Master diffraction regimes: swiftly choose Fresnel or Fraunhofer for any setup.
- Calculate slit and Airy patterns: forecast minima, lobe widths, and detector spots.
- Design apertures quickly: size slits and holes for target sensor coverage at 0.5 m.
- Use Fresnel number effectively: assess approximation errors and pick analytic or numeric methods.
- Simulate and verify beams: perform FFT propagation and measure precise lobe details.
