Near Infrared (NIR) spectroscopy has developed to an important and useful analysis method over the past years. The existence of compact, portable devices offers a lot of applications possibilities, even in harsh environments. Compact devices, mostly based on detector arrays, are quite costly caused...
Grazing-incidence telescope-spectrograph for space solar-imaging spectroscopy The design of a stigmatic grazing-incidence instrument for space applications to solar-imaging spectroscopy is presented. It consists of a double telescope... L Poletto,G Tondello - 《Applied Optics》 被引量: 9发表: 2001年...
Owing to none of the existing method can do it all for oil identification, but a method by near-infrared spectroscopy (NIR) coupled with clustering based on principle components is proposed. Petroleum oil stimulating samples of gasoline, diesel fuel and lubricating oil were employed to develop the...

Infrared spectroscopy analyzes the chemical composition of substances by detecting the interaction of infrared light with molecular chemical bonds, including absorption, emission, and reflection. The typical wavelength range of infrared spectral analysis is 900~2500nm, which mainly reflects the absorption in...
Based on principal component analysis, fuzzy logic methods were introduced to classify different gasoline samples with NIR spectroscopy determination. 测定了不同种类汽油的近红外光谱,在主因子分析的基础上引入了系统聚类法和模糊聚类法对汽油样本集合进行分类和识别研究。 2. Further, with such statistical meth...
The device is based on the principle of NIR spectroscopy having a NIR radiation source (1) and a radiation detector (5). The device has a transmissive structure for the radiography of a sample. Size measuring instruments are provided for the measurement of a size of the sample. The size ...
Among them method based on NIR spectroscopy analysis technique is the most promising blood glucose non-invasive measurement method. The main work of the paper shows as follows: It deeply comparative analyze advantage and disadvantage of three kinds of non-invasive blood glucose measurement methods and...
