Laser Speckle (Random Phases)
This interactive simulator explores Laser Speckle in Optics & Light. Random phased waves: |Σ e^{i(k·r+φ)}|² grain pattern (qualitative). Use the controls to change the scenario; watch the visualization and any graphs or readouts to connect the model with lectures, labs, and homework.
Who it's for: Suited to beginners and first exposure to the topic. Typical context: Optics & Light.
Key terms
- laser
- speckle
- speckle pattern

- light
How it works
A qualitative speckle pattern from superposing random phased waves — why laser pointers look grainy on a wall.
