本文在Moharam等人工作的基础上,对现有的平条纹面介质光栅衍射的二阶耦合波理论作了进一步推广。文中理论分析严格地建立在定态麦克斯韦方程组的基础之上。因此,原则上,按照本文所介绍的方法可以借助计算机得到具有任意所需精度的结果。 本文所研究的对象是平条纹面介质光栅。文中除要求光栅介质具有平面等值面及平面表面外,对光栅结构没有其它限制。本文允许照明光波以任意方向入射(特别是,允许入射面与光栅矢量面成任意夹角)。此外,本文还允许入射光具有任意的偏振状态,并以一系列琼斯矩阵表示光栅的衍射特性。这意味着本文把光栅也当作一种偏振元件来处理。

The Successfully developed SPG-1 laser digital wavefront inter-ferometer is a new type of instrument for measuring the optical surfaces, whichcombines the laser technique、the minicomputer technique and interference tech-nique. This paper covers the design indices and their basis, the design require-ments and design results, the fabrication of the key elements of the interfero-meter, and also the assembly and alignment of it's interference system. The maximum aperture of the instrument is φ80 mm, the highest precisionof measurment is λ/40, the resolution is λ /100. The range of measuring theradius of curvature for A-grade optical spherical test plate is within 500 mm.A interference system should have low noise、high contrast and adjustable bri-ghtness of the fringes. In the Fizeau and Twyman-Green interference systemused, polaroid elements are introduced to form polarization interference systemso that the above requirements can be satisfied rather well. System error is lessthan λ/25. In order to industrialize this digital interferometer, a combinationdesign schemc is proposed.
