Because the variation of the light source and other errors related to light intensity are not so critical for the measurement in this system and some 1/4λ wave-plates affect on the other wavelengths is very little, the retardance can be measured in high accuracy and high repeatability. In principles, the system accuracy can measure any retardance, and can be used in characteristic spectrum analysis of other phase retarders.

由于此系统可忽略光强的波动及与光强有关的误差，且1/4λ波片对多波长测试误差的影响很小，故其有很高的精度和可靠性，可以测试其精度范围内的任意小延迟量，亦可对其他光学相位延迟器件进行光谱分析。

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.

本文给出了一个使用滤光片作为分光器件的近红外光谱仪的控制电路设计方案，其工作原理是：当滤光轮转动时，光源出射光经过滤光轮上的某一滤光片，再照射到样品上，经样品池出射的光携带有样品的吸收光谱信息，滤光轮转动一圈，可得到样品不同波长处的光谱信息，通过后期数据分析可得到样品的成分含量信息。

Young's two slits interference of discrete double light source is numerically simulated,and the curve of visibility, curve of light distribution and interference pattern are solved with different type of line and line width.
