基于STM-32单片机的光纤布拉格光栅温度传感器

s a new type of sensor, fiber Bragg grating sensor is with anti-electromagnetic interference, good insulation properties, corrosion resistance, surveying a wide range of advantages and become the most promising and potential of one of the sensors; Development of high-precision, low-cost fiber grating sensor wavelength demodulation of fiber grating sensor system is a key technology research. At present, several research units of fiber grating sensor demodulation technology research, but for the average temperature of demodulation system generally high cost of not easy to carry. This paper studies to fiber-coupled semiconductor laser as a light source, STM-32-core processors as a single-chip sensor demodulation system, through improved matching of optical path effectively reduces power diode laser light source of instability impact.Data collection, processing and liquid crystal display driver completed by STM-32single-chip, using liquid crystal display FYD12864 temperature.
