几年前,双曝光全息干涉测量术可以测量木板画面上的初始相位,因此有人提出可应用于画板内部探伤(即检测内部分离区域),从局部条纹与平均值的偏离来显示分离区域。运用这种技术时,不允许在重建过程中条纹图形有所改变。所以,米勒提出,在这种情况下应使用实时全息干涉测量术。随着相干光学这一领域进一步的发展,本文认为,可以采用夹层全息照像技术,它既保持了双曝光全息干涉测量术的优点,还具 A few years ago, double-exposure holographic interferometry measured the initial phase on a plank. Therefore, it was proposed that flaw detection could be applied to the interior of the artboard (ie, to detect the internal separation area) and to show the separation area from the deviation of the local fringes from the average. The use of this technique does not allow the bar pattern to change during the reconstruction process. Therefore, Miller suggested that real-time holographic interferometry should be used in this context. With the further development of the field of coherent optics, this paper argues that sandwich holography can be used, which not only maintains the advantages of double-exposure holographic interferometry, but also
