提出了一种记录透射标识二维／三维彩虹全息图的新方法，它直接用散射狭缝光照明二维透射标识，将透射光记录为主全息图；主全息图可按普通二步彩虹一样进行二维／三维的分色、分层次记录，既保持了普通二步彩虹全息的分色、分层次的效果，又突破了普通主全息图面积和长度对再现像亮度和视角的限制，达到大视角、高亮度的效果；对光路的可行性和设置参数进行了详细的分析和讨论，相应的实验得到了满意的结果。
A new method of recording transmissive identification two-dimensional / three-dimensional rainbow holograms is proposed, which directly illuminates the two-dimensional transmissive marks with scattered slit light and records the transmitted light as the main hologram; the main hologram can be the same as a normal two-step rainbow The two-dimensional / three-dimensional color separation and hierarchical recording not only keep the color separation and hierarchical effect of the ordinary two-step rainbow holography, but also break the limitation on the brightness and the viewing angle of the reproduction image by the area and length of the ordinary master hologram Large angle of view, high brightness effect; the feasibility and setting parameters of the optical path are analyzed and discussed in detail, and the corresponding experiments have been satisfactory results.
