FabryPérotin

FabryPérotin is a fictional or hypothetical figure used in some educational and literary contexts to explore the intersection of optics and music. The name is a portmanteau derived from the Fabry–Pérot interferometer, a device for analyzing light via multiple-beam interference, and Pérotin, a medieval composer from the Notre Dame school. The combination emphasizes resonance, harmonic thinking, and interference phenomena across disciplines.

In fictional works, FabryPérotin may be portrayed as a scientist-musician who investigates analogies between spectral lines and musical timbre, or as a symbolic alias for researchers engaging in cross-disciplinary inquiry. In pedagogy, the concept is used as a mnemonic to teach how stable interference conditions depend on cavity length, refractive index, and wavelength, drawing an analogy to the spacing of notes in a scale.

Despite the name's resemblance to real scientific terms, FabryPérotin is not a historical person or a standard scientific term. The actual interferometer is named Fabry–Pérot, after Charles Fabry and Alfred Perot. The addition of Pérotin's name is an informal literary device rather than a recognized scientific designation.
