🔭 Fabry-Perot Interferometer (2D)

A 2D Canvas simulation of a Fabry-Pérot etalon: watch multiple-beam interference between two mirrors build the real Airy-function transmission spectrum, with live finesse, FSR and FWHM readouts.

⚙ Under the hood

A 2D Canvas simulation of a Fabry-Perot etalon: two partially-reflective mirrors form an optical cavity where multiple internal reflections interfere to build the real Airy-function transmission spectrum. Adjust mirror reflectivity, cavity length, and wavelength to watch the finesse, free spectral range, and resonance peaks respond live.
