我们提出分层体积衍射光学元件作为一种新型衍射光学元件，能够在不适合传统全息或衍射光学技术的要求的应用中充当高效光栅。在这种方法中，衍射光学制造方法用于构建模拟体光栅行为的光学结构。我们讨论了分层体积衍射光学元件的衍射特性，并将它们与以前在体积全息光学元件和分层体积全息光学元件中使用的衍射特性进行了比较。然后提出了用于推导结构参数的系统设计过程。我们通过设计原型分层体积衍射光学元件来说明这一过程，以满足星载相干测风激光雷达中光束扫描元件的操作规范。我们使用数值模拟来评估原型元件的性能，包括对制造误差的敏感性。 (C) 1999 年美国光学学会 [S0740-3232(99)01105-9]。
We propose stratified volume diffractive optical elements as a new type of diffractive optical element that is capable of functioning as a high-efficiency grating in applications with requirements not suited to traditional holographic or diffractive optical techniques. In this approach, diffractive optical fabrication methods are used to construct an optical structure that emulates volume grating behavior. We discuss the diffraction properties of stratified volume difffactive optical elements and compare them with those used previously in both volume holographic optical elements and stratified volume holographic optical elements. A systematic design process is then presented for deriving structure parameters. We illustrate this process by designing a prototype stratified volume difffactive optical element to meet the operational specifications for a beam-scanning element in a spaceborne coherent wind lidar. We use numerical simulation to assess the performance of the prototype element, including sensitivity to fabrication errors. (C) 1999 Optical Society of America [S0740-3232(99)01105-9].
