The fibre-optic preforms were produced, the fluoride fibers were fabricated, the anti-stokes fluorescence cooling mechanism was preliminarily researched.
用高纯原料制备了掺镱 1% ,2 % ,3 % m ol的氟锆酸盐玻璃 ,并研制了有芯皮料的氟锆酸盐光纤预制棒 ,拉制了光纤 ,并对它们的吸收谱进行了研究 ,初步探索了它们反斯托克斯荧光制冷机理 。
Spectrum analysis by fluorescence spectrophotometerreveals that the materials appear to produce anti-stokes fluorescence peak with excitation sources atwavelengths longer than those corresponding to the peak of the luminescent bend.
荧光光谱显示,以630nm激发,反斯托克斯荧光峰位于595nm,能量差为0。
This paper, according to the sensibility of anti-stokes light to temperature, making use of many advantages of optical fiber communication, and matching with the electronic control and compensation circuit, designs the system of measuring temperature fields distributed optical fiber sensor for grain depot, the system can come true the stock of corps temperature s real-time controlli.
为此,根据反斯托克斯光对温度的敏感性,利用光纤传输信号的种种优点,配以电子处理与补偿电路,设计了可用于粮库测温的分布式光纤温度场测量系统,该系统可实现对库存粮食温度的实时监控与调整。
