摘要
论述了一种表面散射特性实时光学检测的光纤传感器。采用650 nm、1 310 nm和1 550 nm激光作为光源, 对不同表面粗糙度的样品进行了测试和分析。实验结果表明, 采用多波长的复合光源激光光纤传感器能有效地减小测量的非系统误差, 从而极大地提高了其测量精度; 此外, 波长越短, 粗糙度越大, 散射越复杂。
Abstract
A fiber sensor for optical measuring surface scattering characteristics in real time is introduced. The laser with 650 nm, 1 310 nm and 1 550 nm wavelength is taken as the light source to test and analyze the samples with different surface roughness. Experimental results show that measuring non-systematic error can be reduced effectively by using multi-wavelength composite light source laser fiber sensors. And measuring accuracy is improved greatly. Besides, the shorter is the wavelength, the greater is the roughness and scattering status will becomes more complicated.
