Abstract
- Instead of analyzing the fringe shift that was recently developed by us to detect slight displacement, an alternative approach by monitoring changes in the intensity of the light reflected from a variable-air-gap optical waveguide is presented in this work. Owing to the sensitive feature of the ultrahigh-order modes, a 1.7 nm resolution of displacement measurement is demonstrated without any complicated optical interference system and servotechniques.
