    • Light to be analysed is introduced into a spatially dispersive Fourier Transform spectrometer (105). The resulting image which consists of interference fringes is then relayed into an analyser which superimposes the image onto a single or a plurality of spatial filters (112). The light passing through the spatial filter(s) is then detected. Such detection can be spatially discriminatory or can integrate over space. By comparison of the signal passing through the various filters the level of match to particular spectral characteristics can be ascertained and the properties of the light source, or of an analyte (103) through which the light has passed, can be inferred.
    • 要分析的光被引入到空间色散傅里叶变换光谱仪(105)中。 然后将由干涉条纹组成的所得到的图像中继到将图像叠加到单个或多个空间滤波器(112)上的分析器中。 然后检测通过空间滤波器的光。 这种检测可以是空间上的歧视性的或者可以在空间上集成。 通过比较通过各种过滤器的信号,可以确定与特定光谱特性的匹配水平,并且可以推断出光已经通过的光源或分析物(103)的性质。
