Abstract
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 .关键词
