Paper Abstract

A white-light fiber interferometer working in the spatial domain, using two fiber ends in a hollow tube as the sensing head and an electric-magnetic actuator-mirror reflector as the path compensation-measurement element, is presented. Analysis and preliminary experiments have demonstrated repeatability of 0.02 degrees Celsius within 1 degree Celsius temperature range and repeatability of 0.6 degrees Celsius within 100 degrees Celsius temperature range for temperature measurement. Suggestions for further improving the measurement accuracy are also given.
