A flat object surface and a hologram plate are both illuminated at an oblique angle by laser light of short pulse duration or short coherence length. Only those parts of the object surface are holographically recorded that correspond to a small-pathlength difference between object beam and reference beam. The holographic plate therefore corresponds to an infinite set of gated viewing systems triggered by the traversing reference beam. Scanning along the processed plate produces a continuous-motion picture of the light in flight. This new technique probably represents the ultimate in high-speed photographic recording, as no mechanical or electrical inertia is involved.
一个平面物体表面和一张全息图板都由短脉冲持续时间或短相干长度的激光以倾斜角度照射。物体表面只有那些对应于物光束和参考光束之间小光程差的部分被全息记录下来。因此，全息图板相当于由移动的参考光束触发的无限组选通观察系统。沿着处理过的板进行扫描会产生飞行中光的连续动态图像。这项新技术可能代表了高速摄影记录的极致，因为不涉及机械或电惯性。
