Paper Abstract

This paper presents a position monitoring system incorporating high birefringent optical fiber and white-light interferometry, where the measurement process takes place within the optical fiber medium. With a novel scheme of relative position detection, the effects of temperature variation can be largely eliminated. A position monitoring range of 200 mm, accuracy of about 3 mm with temperature stability to within less than 0.5 percent was experimentally demonstrated.
