We report the fabrication of large-area holographic diffraction gratings on a curved surface from transferred photopolymer films by introducing a water-soluble interlayer. The holographic gratings on a curved surface have a diffraction efficiency of 63%, which is 80% of the recorded holographic film on a flat surface. By transferring a recorded holographic grating to a flat substrate, we obtained rainbow holographic gratings under white light illumination. This can be explained by the deformation of the holographic gratings. Our result provides a low-cost method for fabricating diffraction optical elements on a curved surface for optical systems.

使用转移的光敏聚合物薄膜在曲面上的大面积彩虹全息衍射光栅

我们报道了通过引入水溶性中间层在转移的光敏聚合物薄膜上形成曲面的大面积全息衍射光栅。曲面上的全息光栅的衍射效率为63,这是 80平面上记录的全息胶片的轮廓。通过将记录的全息光栅转移到平坦的基板上,我们在白光照射下获得了彩虹全息光栅。这可以通过全息光栅的变形来解释。我们的结果提供了一种在光学系统的曲面上制造衍射光学元件的低成本方法。
