Abstract
Temperature measurement by laser is an advanced method for measuring the temperature of optical material in vacuum or any heat insulation situations. It is accurate, rapid, non- touching and non-contaminate. But up to now, it can only be done by manual counting the laser interference fringes, which restricts the wide application of the method. Normal fringe counter can not be used, because the whole laser spot with the fringes often moves during the heating process. Using a CCD-camera and special computer software, we developed a real-time measuring system that can track the spot automatically, and currently show the temperature-time curve. The design, feature, setup and application of this measurement system are described and discussed.
