摘　　要：根据全息照相原理，理论上只要将物光和参考光的光路设计得能够发生干涉，就可以拍摄出全息照片，因此拍摄全息照片的光路不是唯一的。不同光路拍出的全息照片的效果有所不同，可以根据不同的被摄物体，选择不同的光路，以达到最佳的拍摄效果。首先介绍几种常见全息照相的光路，对它们的优点和不足进行分析，进一步提出用多个物光束拍摄全息照片的新方法，并对光路的快速调整方法进行系统的探讨。The light path to take photos of hologram is not unique, because according to the principle of holography, we can take a holographic picture as long as the object light path and the reference light path are theoretically designed to make optical interference occur. Different paths of ray lay out different effects of optical holographic pictures. We may choose different paths of ray according to different objects in order to achieve the best photography effect. This paper introduces several kinds of common holographic optical paths, analyze their merits and weaknesses, further puts forward a number of new methods to take pictures of hologram using many object beams,and carries on a system discussion on the quick-adjusting method of light path.
