Michelson White-Light Interference Lab Tutorial

Teaching team: Yin-Kai Yu, Lianghong Mo, Zhencheng Huang.

The first publicly available, systematic video tutorial for the Michelson white-light interference experiment.

In the theory segment we view the interference pattern from a field perspective. Two virtual sources equally spaced along the optical axis form a family of confocal hyperboloids in space, and the laser interference pattern corresponds to cross-sections of that field. White-light interference adds many families with slightly different spacings; they only overlap near zero optical path difference, which naturally limits the observation window. This viewpoint is far more direct than the traditional thin-film analogy.

We also summarize practical tricks for widening the workable region: shrink the separation between the virtual sources and use a rare-earth lamp with higher coherence than white light. These tricks dramatically boost the success rate and lower the operational difficulty for students.


Neighbors on the Web

(I observe them. Just like neighbors in a physical community: some are close friends, while others don't know me at all.)
