大场景、大景深全息照相术已有一些文章介绍与报道[1-3].近年来,我们初步获得了景深为250cm,场景面积为100×250cm2和视场角优于120°的广角大场景全息图[3].为进一步提高大场景全息图的质量,普及大场景全息术,从而开拓大场景的全息应用,本文对大场景全息照相实验中的若干特殊 Large scenes, large depth of field holographic photography has been introduced and reported some articles [1-3]. In recent years, we initially obtained a depth of field of 250cm, the scene area of ​​100 × 250cm2 and angle of view better than 120 ° wide-angle scene Hologram [3] .In order to further improve the quality of large scene hologram, popularize large scene holography, so as to open up the holographic application of large scene, this paper studies some special
