A uniform coherent light source, a filter and a receiving screen are designed in computer.
在计算机上模拟一个均匀相干光源、个滤波器和一个接收屏。
Finally, experiments are done by using a red high brightness LED to be the partial coherent light source.
最后，用红色高亮led作为准单色光源进行了验证实验。
Therefore, the characteristics of ECSL should be studied farther to acquire the coherent light source with more accurate and stable lasing wavelength.
因而有必要对其进行深入细致的研究，以期获得更高精确度和更稳定激射波长的相干光源以满足信息高速、大容量传输的要求。
The results show that logarithmic light intensity fluctuation variance will be less when light source coherence becomes worse, i. e. it becomes into partially coherent light.
其结果表明，当光源的相干性变差，即变为部分相干光后，对数光强起伏方差变小；
It was found that the coherent length became shorter and the spectrum resolving power became lower as a result of solid Angle produced by the extended light source.
分析表明，扩展光源存在的立体角导致系统的相干长度变短，光谱分辨率降低。
