In this study, the temperature measurement system is designed and experimentally performed with a single and array Fiber Bragg Grating (FBG) based temperature sensor. A 1532.032 nm seramic plated and a 1536.674 nm metal plated FBG sensors are used. The temperatures of the single and array sensors are changed between 30 degrees C to 100 degrees C and optic signal variations at the output are investigated with used swept laser technique. Consequently, temperatures are measured accurate and fast with the precision of 0.5 degrees C.
