查询词典 gamma ray

The article gives a design of an NIR instrument with filter. The working theory of the instrument is: during wheel running a circle , ray from light source irradiates the sample after it through a certain filter of filter wheel, so ray would carry the absorption spectrum of sample . We can know components of the sample by analyzing the ray . Filter wheel is its light splitter.
