摘要: 介绍了一种用连续激光制作动态自发光物体体视彩虹全息技术,为火焰场的温度分布及气流的浓度分布等领域的研究提供了新的实验方法.先用自制的透镜线阵照相机拍摄动态自发光物体的初级体视图,然后用连续激光照明初级体视图,透镜线阵此时不仅起到成像作用,而且起到了彩虹全息术中的狭缝作用.制作了动态自发光物体(蜡烛光)的体视彩虹全息图,并给出了实验结果.实验结果表明该方法是可行的.Abstract: A new technique of fabricating stereo-rainbow holograms is presented which can record dynamic and spontaneous fluorescence objects by continuous laser.The technique also provides a new way to study the temperature distribution in a frame field, the concentration distribution of gals-flow and so on.Firstly, we take the primary stereoscopic picture of a dynamic and spontaneous fluorescence object by the linear lens array camera made by ourselves.Then continuous laser illuminates the primary stereoscopic picture and the stereo-rainbow hologram is fabricated.Here the linear lens array not only has imaging capability, but also acts as the slits of rainbow holography.In our experiments we fabricate stereo-rainbow holograms of candle's frame.The results prove that the technique is feasible.The paper presents the principle of the proposed technique and the experimental result.
