High-response optical fiber temperature sensor
High-response optical fiber temperature sensor
The high-response optical fiber temperature sensor (FOT-HERO) is a very compact and highly accurate sensor. It is completely unaffected by electric and magnetic fields (EMI - Electro Magnetic Interference). The sensing element is made of Si:H (silicon) and has a small size of 150×150μm, making it suitable for research and development of Electronic Explosive Devices (EED). The response time is less than 1ms, and it does not interfere with the EED circuit. The sensor can accurately measure the temperature of the bridge wire even when exposed to EMI. The temperature range of the sensor is 0 to 120°C. Since there is a proportional relationship between the current flowing through the bridge wire and the temperature, it is possible to study ignition conditions caused by interference such as EMI. The measurements are based on detecting changes in the refractive index of Si:H caused by temperature variations.
