远程全息实验已经在长达12公里的距离上进行。获得了后向反射器和Scotchlite物体的全息图和图像。参考波由放置在物体旁边的后向反射器提供，光源是调q红宝石激光器。所获得的分辨率随大气观测条件的变化而变化，范围从3视距到0.5视距。遇到的主要实际问题是探测器饱和，这是照相胶片动态范围有限的结果。使用低对比度显影剂只能部分缓解这个问题。
Long-range holographic experiments have been performed over distances as large as 12 km. Holograms and images of retroreflector and Scotchlite objects were obtained. The reference wave was supplied by a retroreflector placed next to the object, and the source of illumination was a Q-switched ruby laser. Resolutions obtained varied with atmospheric seeing conditions, ranging from 3 see of arc to 0.5 see of arc. The primary practical problem encountered was detector saturation, a consequence of the limited dynamic range of photographic film. The use of a low contrast developer only partially alleviates this problem.
