光譜儀用了一塊凹面衍射光柵,第一級光譜的色散度為42埃毫米。The polarization - dependent diffraction characteristics of the metallic echelle and the total internal reflection ( tir ) types of diffraction gratings are studied, and optimal design method based on the hybrid diffraction method is presented
針對目前衍射光柵器件在損耗、偏振敏感性等方面的不足,本文對金屬反射型以及內全反射型凹面光柵的偏振相關的衍射特性進行了矢量分析,並基於混合衍射方法提出了更為準確有效的優化設計方法。
