Thermal expansion measurements using Fabry-Perot etalons |
摘要 |
A method for determining the thermal expansion coefficient of a substance comprises, determining at each of two or more temperatures the absolute position of more than one resonant interference peaks of a Fabry-Perot etalon whose optical path is defined by said substance and calculating said coefficient from observed difference(s) in wavelength or frequency of said positions at said two or more temperatures.
