Abstract
In this study, a plastic fiber-optic temperature sensor is fabricated using TSCM(thermo sensitive clouding material) which changes its light transmittance with temperature and the characteristics of this sensor are evaluated. The fabricated fiber optic temperature sensor is the reflector type using a Y-coupler. The optimum light source and reflector are decided by measuring the amount of reflected light through TSCM. Also, the optimum distance from the end of sensor to the surface of reflector is determined. Then the relationship between the amount of measured reflected light and the temperature of TSCM is found.
