| 摘 要： | 针对双折射滤波器中器件损耗的情况,同时为了改善滤波光谱的次极大,设计了一种新型滤波器,并从原理上作了分析,此新型滤波器与原有多级滤波器相比,主要的改进在于减少了所用偏光镜的数目,从而提高了出射光的透过率.以Schoolman型石英晶体双折射滤波器为例,将此新型滤波器与原有结构进行了比较,从理论上分析了在考虑各器件损耗的情况下的滤波特性,结果表明,此滤波器具有减少出射光损耗的显著效果.

| Abstract: | This paper designs a new type of filter in order to reduce the loss of birefringent filter's components,as well as to enhance sideband energy of filtration spectrum and give a theoretical analysis.Compared with former multi-level filters,this new-type one is mainly improved in the transmittance of output light by lessening polarized polarized lens.Taking schoolman quartz crystal birefringent filter for example,this paper makes a comparison of this new-type filter with its former structure and analyses theor... |
