本文对衰减振动全息减法干涉条纹进行了分析。结果表明,全息减法的节线位置容易确定。此外,文中还提出用两张减法全息照片来测定衰减系数。
In this paper, the attenuation vibration holographic subtraction interference fringes were analyzed. The results show that the nodal position of the holographic subtraction is easy to determine. In addition, the paper also proposed using two subtraction hologram to determine the attenuation coefficient.
