摘要
通过分析两步法制彩色全息图中全息图空间带宽积与物体大小、全息图记录距离的关系,提出了一种拍摄大尺寸物体彩色全息图的方法。经编码,设置参数,在视窗处平面记录下三分色全息图, 以保证用最小的幅面记录下物体的完整信息,并且H1rgb处于同一平面经原参考光的共轭光再现时,他们的再现像能完全重合; 将H1rgb再现,获得大视场的物光波信息,三基色物波信息重合后,用光学方法记录大幅面的彩色全息。该方法能提高全息图再现像的视场和解决大尺寸物体的全息图难拍摄问题。 经实验验证,该方法能将全息图再现像的视场提高6倍左右。
Abstract
Based on analyzing the relationship among the hologram spatial frequency, the object size and the hologram record distance in making the color hologram by two-step method,a method for making color hologram of large objects was proposed. Firstly, the tricolor hologram H1rgb was recorded in visual plane after intercalating right parameters, so as to make sure the full information were recorded in the least area and when H1rgb placed in the same plane, their reappeared images could overlap. Then, the overlapped images were recorded to acquire the color hologram after the information of objects were enlarged by the conjugate light. This method can enlarge the field of view(FOV) and sit for making hologram of large objects. It is verified by experiment that the FOV can be widen by 6 times.
