光纤和全息双频光栅结合测振法

Double Exposure Holographic Moire

本文介绍一种全息莫尔方法。用全息底片先在物体位置上拍摄投影条纹,平移后再拍制被相同条纹照明的物体的全息图。在全息图的再现像中便出现莫尔条纹。同时给出这种方法的两个改进光路。

A Moire method is proposed in the present paper. The holographic plate first at the position of object is exposed with the projective fringes. After translating the plate, the hologram of object illuminated with the same fringes is taken again. Moire fringes appear in the reconstruction image of the hologram. Two improving geometries of this method are also given.
