信息光学 全息光栅 衍射效率 温度响应特性 information optics holographic grating diffraction efficiency temperature dependence
摘要
针对全息材料的热膨胀,研究了温度变化时,全息光栅条纹结构的变化情况并对多块不同制备条件下记录的反射型全息光栅进行20 ℃到80 ℃间的温度特性测量。测量结果表明,反射型全息光栅的衍射布拉格峰随温度变化而平移,最大衍射效率也因此改变。此外,反射型全息光栅对温度变化的敏感性与其条纹周期有关。
Abstract
According to the thermal expansion of the holographic material, the article suggested the possibility the fringes structure of the holographic grating would change when the temperature changed.Temperature dependence measurements were done from 20 ℃ to 80 ℃ on several reflection holographic grating, recorded under different conditions.The measurement results indicated that the diffraction Bragg peak of reflection holographic gratings shifted when the temperature changed, and the maximum diffraction efficiency changed as well.Moreover, the sensitivities of reflection holographic gratings on temperature change are related with the fringes period of the grating.
