为了研究机械应力对石英滤波输出的影响,基于石英晶体的弹光效应,推导了石英晶体双折射率与不同方向机械应力之间的关系,并进行了数值模拟。采用了Ultra-6600系列紫外-可见分光光度计搭建了实验系统,得到了立奥型石英双折射滤光片的透射光谱图,并对光谱图进行了研究与分析。结果表明,在不同方向机械应力作用下,立奥型石英双折射滤光片的中心波长发生漂移;大小为0.0025N/m2机械应力沿Ox1轴、Ox2轴、Ox3轴方向作用,石英滤波片中心波长向长波长方向的漂移量分别约为0.4nm,0.6nm,1nm。这一结果对石英双折射滤光片的封装制作、正确设计和使用是有帮助的。

In order to study influence of mechanical-stress on quartz filter output , based on the elasto-optical effect of quartz crystal, the relationship between birefringence of quartz crystal and mechanical stress in different directions was analyzed .After numerical simulation, the experimental system was set up by using UV-visible spectrophotometer of Ultra-6600 series and the transmission spectrum of a Lyot quartz birefringence filter was studied and investigated .Theoretical simulation and experimental results show that central wavelength of the Lyot quartz crystal birefringence filter will drift under mechanical stress at different directions.The drifts of central wavelength of a Lyot quartz crystal birefringence filter are 0.4nm, 0.6nm and 1nm respectively when mechanical stress is 0.0025N/m2 along the direction of Ox1 axis, Ox2 axis, Ox3 axis.The research is helpful for manufacture , design and application of quartz birefringence filters .
