设计了一种基于磁流体填充D型微结构光栅的太赫兹波段温度和磁场传感器。通过结构优化，实现了温度和磁场的高灵敏度测量。最高温度灵敏度为233.88 pm/C，最高磁场灵敏度为214.802 pm/mT。当传感器整体结构尺寸变化± 0.1%时，温度或磁场传感器的最大绝对偏差分别为0.018 pm/C和0.03 pm/Oe，同时采用双参数解调矩阵有效地克服了串扰问题。
A terahertz band temperature and magnetic field sensor based on a magneto-fluid-filled D-type microstructure grating is designed. The high-sensitivity measurement of temperature and magnetic field is realized by optimizing the structure. The highest temperature sensitivity is 233.88 pm/C, and the highest magnetic field sensitivity is up to 214.802 pm/mT. When the overall structure size of the sensor was changed by ±0.1 %, the maximal absolute deviation of temperature or magnetic field sensor is 0.018 pm/C and 0.03 pm/Oe. At the same time, the dual-parameter demodulation matrix is used to effectively overcome the crosstalk problem.
