Cooling system by using Fiber Bragg grating as temperature sensor / Khairulazrin Abdullah

This paper proposes to design a cooling system by using Fiber Bragg grating (FBG) as a temperature sensor. The metrology system was developed for detecting temperature by monitoring shifted of Bragg wavelength, the movement of Bragg wavelength shifted are used to indicate the temperature change at surrounding, when the temperature reach the set maximum surrounding temperature, the cooling system will be turn on and maintain the environment temperature. The optical fiber will provide the broadband light source and FBG will reflect the Bragg wavelength and transmit other. The system is based on FBG as a physical quantity sensor, power supply to supply voltage to cooling system and wavelength meter is used as a collecting data instrument. The temperature will be controlled by the intensity of light bulb. The system will be running under the Agilent VEE software. Agilent VEE will be used as a tool to display the data for temperature variation
