Abstract

In this study, an interferometer measurement module which has the capability to determine the thermal expansion coefficient of the linear translation aluminum alloy stage for the linear displacement is proposed. This structure consists of two Fabry-Pérot interferometers installed on the stage at different positions for investigating the thermal effect. In the optical arrangement, Fabry-Pérot optical cavity is composed of two plane mirrors and a charge-coupled device(CCD) for inspecting the swept interference fringes induced by the temperature drift. In addition, the constructed measurement module possesses compact optical structure and optimal analysis method. For the high precision laser system, it can provide an estimation for the displacement measurement during the temperature change of six degrees.
