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.)
- Xiao Yao — my beloved.
- Zhao-Huan Yu — a teacher of mine; my web template comes from his site. He also has excellent QFT lecture notes.
- Lianghong Mo — dear friend; the familiar look is absolutely my fault.
- Yuchen Wang — another close friend; same template heritage.
- Zhi Zeng — also part of the extended template family.
- Yuhao Li — younger schoolmate; we organized lots of fun events together.
- Shi-Xin Zhang — he seems to have observed my page as well.
- Yuchen Wang — a big shot. Shares the same name pronunciation as the other Yuchen, so I found him early on.
- Tong Chen — a name everyone knows.
- Xuejia Yu (Sugar Yu) — first met via Zhihu, later found even more overlaps.
- Tian-Hua Yang — heard his legends since childhood... even though we’re the same age. His office is next to Lianghong Mo's.
- Zhong-Zhi Xianyu — a master I discovered while studying QFT in depth.
- Tinikov — don't know who this is, but he believes the internet will reconnect one day.
- Zhe Feng — met in a WeChat group, then surprisingly became classmates.
- Yuchen Guo — a big shot. Just one cohort ahead yet so productive. I truly admire him.
- Yi-Ming Ding — a big shot; amazingly prolific and interesting.
- Ning Xia — conference friend; his work is rigorous and inspiring.
