four step phase shifting hologram

在矿井光轴上的全息图，这四个干涉图被捕获并存储在thememory。使用该信息，可以重建theobjective波的波函数。重建可以在digitalcomputers容易地进行。它可以从该方法有四个干涉arenecessary检索原始对象波可以看出。然而，也能够usefewer干涉图在此过程中，记录和重构originalinformation:Inthe on-axis hologram, the four interferograms are captured and stored in thememory. Using this information, one can reconstruct the wave function of theobjective wave. The reconstruction may be easily performed on digitalcomputers. It can be seen from this method that four interferograms arenecessary to retrieve the original object wave. However, it is possible to usefewer interferograms in this process to record and reconstruct the originalinformation
