Any motion of the scene during the exposure of a hologram results in a spatial modulation of the recorded fringe contrast. On reconstruction, this produces a spatial amplitude modulation of the reconstructed wavefront, which results in a blurring of the image, not unlike that of a conventional photograph. For motion of the scene sufficient to change the path length of the signal arm by a half wavelength, this blurring is generally prohibitive. This paper describes a proposed holographic technique which offers promise for front light resolution of targets moving at high speeds, heretofore unobtainable by conventional methods.
在全息图曝光期间场景的任何运动都会导致所记录条纹对比度的空间调制。在重建时，这会产生重建波前的空间幅度调制，从而导致图像模糊，这与传统照片的模糊情况并无不同。对于场景运动足以使信号臂的光程长度改变半个波长的情况，这种模糊通常是不可接受的。本文描述了一种提议的全息技术，该技术有望实现对高速移动目标的前向光分辨率，而这是传统方法迄今无法实现的。
