摘要

作者简介:在含蔗糖水的模拟过程样品上测试了一种新型全纤维光谱仪,该光谱仪具有工业过程测量的理论优势。该光谱仪采用色散傅立叶变换方法,将超连续光谱激光器与时间波长分离光纤相结合。采用多变量曲线解析法,从蔗糖和水两种组分溶液的光谱中分离出蔗糖和水的纯光谱和浓度分布。新的光谱仪在快速和抗振动测量方面具有很大的潜力,但需要进一步的研究来确定其在更复杂和真实过程样品上的性能。

First trial with an all-fibre near infrared spectrometer evaluated by multivariate curve resolution
Author Summary: A novel all-fibre spectrometer with theoretical advantages for industrial process measurements was tested on simulated process samples of water with sucrose. The spectrometer uses the dispersive Fourier transform method and combines a supercontinuum laser with a time-wavelength separating optical fibre. Multivariate curve resolution was used to resolve the pure spectra and concentration profiles of sucrose and water from spectra of solutions with both constituents. The new spectrometer has great potential for rapid and vibration-robust measurements, but further studies are needed to determine its performance on more complex and real process samples.
