摘要:

依据Mie散射理论,分析散射粒子与散射光强的关系,在入射波长、入射光强、探测距离、粒径尺寸参量、折射率,后向散射角已知时,后向散射光强就与粒子数浓度成正比。在实验中,把激光信号通过双D型光纤传感器中的一支光纤射入陶瓷泥浆,另一支光纤接收陶瓷泥浆颗粒对激光信号的后向散射光线。记录、分析这组电压值和陶瓷泥浆质量分数的关系后知道:含陶土量为0%~40%之间的数据曲线是非线性的,在陶土含量为40%~60%之间的数据曲线是线性的。分别检测质量分数为40%、60%的陶瓷泥浆样本,激光后向散射光线经过信号处理得到电压值,获得一个直线方程。分别检测质量分数为40%~60%之间的多个陶瓷泥浆样本,得到一组与陶瓷泥浆样本质量分数相对应的电压数值,从而证明了直线方程的正确性,也进一步证明后向散射光强与粒子数质量分数成正比这一结论的正确性。

Abstract:

Based on the Mie scattering theory, if the incident wavelength, incident intensity, detection distance, particle size, refractive index and backscatteringangle are  all known, the intensity of backscattering light is proportional to particle concentration. In the experiment, one of the laser optical fibers irradiates ceramic mud through a doubleD optical fiber sensor, the other receivesthe backscattering laser light that goes through the ceramic mud. The measured voltage andits corresponding ceramic mud’s argil content relationship was analyzed, whichwas nonlinear for ceramic mud of mass fraction between 0%~40%, and linear for ceramic mud of mass fraction between 40%~60%.The ceramic mud of mass fraction of 40% and 60% were measureds and a line equation was obtained  by signal processingbackscattering laser changes into voltage. Then several ceramic mud samples whose mass fractionchanging was between 40%~60% were measured, and the result showed  the valiity of the line equation, and that  the backscattering light was proportional to the mass fraction of the  particle.
