绪言:掺杂纤维稀土的光学温度传感器是1979年NASA在屏蔽研究中的产物,这是识别光学温度和压力感受的新方法。稀土探针被认为是最有前途的。制造了两种纤维光学传感器:一种传感器采用稀土铕;另一种采用稀土钕。采用掺杂稀土的纤维探针理由可概括如下:稀土离子能很快的化入到大量的玻璃基质材料中;稀土离子具有光学跃迁能力,能提高在可见光和靠近红外波长处的吸收性,并有大量地低能级,光的跃迁就是这些低能 INTRODUCTION: Optical temperature sensors doped with rare earth fibers were the product of NASA’s shielding study in 1979, a new method of identifying optical temperature and pressure sensation. Rare earth probes are considered the most promising. Two fiber optic sensors were fabricated: one with rare earth europium; the other with rare earth neodymium. Rare earth doped fiber probes can be summarized as follows: rare earth ions can quickly into a large number of glass matrix material; rare earth ions have optical transition ability to increase in the visible and near infrared absorption of the wavelength, and A large number of low-level, light transition is these low energy
