绝对程差条纹可以用园偏振光作物光的偏振全息术进行分离。但是,在再现虚像的光强表达式中存在的等差项只能用转动全息图与观察者之间的偏振镜才能消除。本文提出另一种用消偏振的光作物光的偏振全息术,由此导出的光强表达式中,等差项完全被消去了。若分别用两个参考光照射用此法拍摄的一张两次曝光的全息图,也能分离两个绝对程差条纹族。

Absolute path difference stripes can be separated using polarization-holography of the field-polarized crop light. However, the difference in the expression of the intensity of the rendered virtual image can only be eliminated by rotating the polarizer between the hologram and the observer. In this paper, we propose another polarization holography using depolarized light crop light, and the resulting light intensity expression, the equidistance is completely eliminated. If two reference beams are used to illuminate a double-exposure hologram taken by this method, two absolute path difference stripes can also be separated.
