当使用全息术记录飞行中的光时，存在两种不同类型的波前的表观畸变。第一种畸变是所有类型的超快选通观察系统所共有的，并且像相对论现象一样，它是由用于观察的有限光速引起的。第二种失真是由全息过程本身产生的，并且是由用作参考光束的光脉冲的有限速度引起的。通过使用第二失真来补偿第一失真，可以操纵或消除明显的波前倾斜或失真，从而便于波前或其他物体的3D形状的测量。作为参考光束的共轭的重建光束导致三个有趣的效应，其中之一是记录脉冲的再发射。
When light-in-flight recording by holography is used two different sorts of apparent distortion of the wavefronts exist. The first distortion is common to all types of ultrafast gating viewing system and like relativistic phenomena it is caused by the limited speed of light used for observation. The second distortion is produced by the holographic process itself and is caused by the limited speed of the light pulse used as a reference beam. By using the second distortion to compensate for the first it is possible to manipulate or eliminate apparent wavefront tilts or distortions so that measurement of the 3-D shape of wavefronts or other objects is facilitated. A reconstruction beam that is the conjugate of the reference beam results in three interesting effects, one of which is the reemission of the recorded pulse.
