全息地形立体图是将传统的光学机械立体投影术与全息术相结合，用航摄像对合成为一张具有一定焦深的近像面全息图。它既具有像面全息图衍射效率高，可以用扩展的白光光源再现的优点，也具有体全息图一定的波长和角度选择性。本文介绍了拍摄这种立体图的装置和方法，并从理论上对实验结果进行了一些分析，最后指出了它的应用前景。
Holographic terrain three-dimensional map is the traditional optical mechanical stereoscopic projection combined with holography, the use of aerial imaging pairs into a certain depth of field near-surface hologram. It not only has the advantages of high diffraction efficiency of surface hologram, which can be reproduced by extended white light source, but also has the certain wavelength and angle selectivity of volume hologram. This paper introduces the device and method of shooting this kind of stereogram, analyzes some experimental results theoretically, and finally points out its application foreground.
