将平面参考波记录的全息图沿Ｘ轴、Ｙ轴或Ｚ轴旋转１８０°后再现，再现的全息物像清晰；相对于原物像，原物光方向的再现像呈现与旋转相同的位形变化，如反、倒、赝等特点，组合起来共可产生１６种不同的物像形态；本文对物像的各种形态给出了解释，并给出成像具有的对称特点和表达。 The hologram recorded by the plane reference wave is rotated by 180 ° along the X-axis, Y-axis or Z-axis and is reproduced. The reconstructed holographic image is clear. Compared with the original image, the original image is reproduced in the same direction as the rotation Such as inversion, inversion and pseudoposition, can produce a total of 16 different forms of object images in combination. In this paper, various forms of object images are explained, and the symmetrical features and expressions of images are given.
