摘要

    摘要
  • 摘要: 空间太阳望远镜中的双折射干涉滤光器对于温度的变化十分敏感，传统的滤光器在空间环境中很难做到高精度的温度控制。改进传统滤光器的结构，在每一单级中加入LCVR(液晶位相延迟器)，通过LCVR主动引入的附加位相延迟补偿由于温度波动引起的晶体位相延迟，可使滤光器透过率峰值波长始终保持稳定。以Lyot滤光器为研究对象，通过理论计算和模拟分析证明了该方法的可行性。该方法应用到空间双折射干涉滤光器可以使滤光器在卫星制造部门提供的环境温度下不使用任何温控系统依然正常使用，成功解决了空间双折射干涉滤光器温控精度的问题。由于摒弃了传统的两级温控装置，有效减小了滤光器的体积，减轻了滤光器的质量，使其更符合空间有效载荷的使用要求。
    Abstract: The birefringent filter on space solar telescope is sensitive to the change of temperature，however, the precise temperature control of the traditional birefringent filter is difficult to achieve. An active compensation method which added a liquid crystal variable retarder (LCVR) in each single-stage of birefringent filter and introduced an additional retarder to compensate the delay caused by temperature fluctuation was put forward. This allowed the wavelength of the birefringent filter transmission peak to remain stable. The Lyot filter was studied, and the theoretical calculations and simulation proved the feasibility of this method. By applying the method to the spatial birefringent filter, the good performance of the filter could be remained without any temperature control system at the temperature provided by the satellite manufacturer, and the accurate temperature control of spatial birefringent filter was achieved. Since the traditional two-stage temperature control device was abandoned, the volume and weight of the filter were effectively reduced which met the requirements of space payload.
