摘要
理论分析发现,在连续加载的情况下,光纤珐珀应变传感系统的测量误差曲线中会出现锯齿波现象。该现象主要是由光源的光谱形状引起的。为此,设计了一种新型的精密连续加载定标系统对光纤珐珀应变传感系统测量误差的细节进行分析,试验结果证明了这一点,并且,由该现象所导致的误差有10微应变。
Theoretical analysis found that, in the case of continuous loading, fiber Fabry-Perot Strain Sensor System for the measurement error will appear sawtooth curve phenomenon. The phenomenon mainly by the light source caused by the spectral shape. To this end, the design of a new type of precision calibration system for loading of fiber-optic Fabry-Perot Strain Sensing System the details of measurement error analysis, test results prove this point, and, by the phenomenon caused by the error has 10 micro - strain.
