在二步周视彩虹全息图制作光路中布置一块大孔径的菲涅耳螺纹透镜及预置狭缝，既可获得具有较大观察口径的周视彩虹全息图，又可大幅度提高记录时光能的利用率。文中给出了理论分析与实验结果。
In a two-step peripheral viewing of a rainbow hologram production light path, a large-aperture Fresnel thread lens and a preset slit are arranged to obtain a peripheral rainbow hologram with a larger observation aperture and greatly improve light energy during recording Utilization rate. The paper gives the theoretical analysis and experimental results.
