In the temperature measurement , using a means of the optical fiber homochromous radiation temperature measurement , the mathematical model is created , and the temperature is monitored in real time . in the displacement measurement , the reflex mode method of displacement measurement of optical fiber is adopted . in order to eliminate the unstability of measurement system created by the illuminant receiving outside disturbance , the system designs referenced channel to assure the reliability of measurement and monitor the change of displacement in rea time
