Fresnel Diffraction Simulation
Near-field diffraction pattern from phase summation
What Is Fresnel Diffraction?
Fresnel Diffraction refers to near-field diffraction pattern from phase summation in optics & light. This page visualizes the phenomenon with interactive controls so you can change parameters and observe how the model responds.
What To Observe
- Watch how the visual pattern or system response changes as you adjust the controls for Fresnel Diffraction.
- Relate each visual change to the core phenomenon shown here: near-field diffraction pattern from phase summation.
- Use repeated runs with one parameter changed at a time to build intuition.
