A method is described for lessening the stringent vibration isolation requirements associated with conventional cw holography. This is accomplished by focusing a portion of the laser illuminating beam to a spot on the object, which then serves as a speckle reference beam for recording the object. In addition to the reduction of vibration isolation requirements, other features of the technique are as follows: Several holograms of the same scene, with different viewing directions, can be recorded simultaneously without additional reference beams, and vibration isolation requirements on the holographic plate are no greater than those associated with conventional photography. The method can also be used to determine relative phase between two points on a vibrating surface. In pulsed holography, the method can be used to eliminate residual fringes between recordings of pulsed holographic interferograms.
描述了一种降低与传统连续波全息术相关的严格隔振要求的方法。这是通过将激光照明光束的一部分聚焦到物体上的一个点来实现的，该点随后用作记录物体的散斑参考光束。除了降低隔振要求外，该技术的其他特点如下：可以在不使用额外参考光束的情况下同时记录同一场景的多个不同观察方向的全息图，并且全息图板上的隔振要求不高于与传统摄影相关的要求。该方法还可用于确定振动表面上两点之间的相对相位。在脉冲全息术中，该方法可用于消除脉冲全息干涉图记录之间的残留条纹。
