Where can I find out more about how thermal effects in the LIGO optics are controlled for?
Basically, I want to understand how it's possible to measure a distance change on the femtometer scale.
- selimthegrim 11y agoYou probably want to read about their active isolation measures. Then you should find anything by Vladimir Braginsky you can get your hands on. This is a good start: http://www.amazon.com/Quantum-Measurement-Vladimir-B-Braginsky/dp/0521484138 http://www.amazon.com/Quantum-Measurement-Vladimir-B-Bragins...
- JabavuAdams 11y agoGreat! Thanks. My local university has this.
