This paper examines the feasibility of producing multiplexed Bragg gratings for use as diffractive optical elements (DOEs) by coherent optical replication of a surface-relief phase grating into thick-film photosensitive materials. The use of such DOEs in light guide plates (LGPs) for optical imaging systems ensures energy-efficient light input into and output from LGPs and allows one to minimise their weight and size. We present simulation results for the interference structure fabrication process and recording of a series of multiplexed diffraction gratings in photosensitive materials.

通过光学复制工艺在光敏材料中进行布拉格光栅刻印

本文研究了通过将表面浮雕相位光栅相干光学复制到厚膜感光材料中来生产用作衍射光学元件（DOE）的多重布拉格光栅的可行性。在光学成像系统的导光板（LGP）中使用此类DOE，可确保进入LGP和从LGP输出的高能效光，并使其重量和尺寸最小。我们提出了干涉结构制造过程的模拟结果，并在感光材料中记录了一系列多路复用衍射光栅。
