【摘要】 根据测量所要求的动态范围、线性度、灵敏度,通过数值计算得出落管中双波长温度测量中的工作波长及带宽的最佳范围,结合实际情况最终确定工作波长为 1.4 μm 和 1.55 μm,其带宽均为 0.03μm。更多还原

【Abstract】 According to the dynamic range of measurement, linearity and sensitivity, the optimal range of working wavelengths and the corresponding bandwidths were determined by numerical calculation. Combined with practical factors, two working wavelengths of 1.4 μm and 1.55 μm were selected, whose bandwidths both being 0.03 μm.更多还原
