实时法是全息干涉术的一种方法,与全息干涉术的双曝光法和时间平均法相比,有许多显著优点.但因为在精确复位、胶膜收缩等方面存在一些问题,因而应用不普遍.我们主要在精确复位方面做了些工作.
Real-time method is a method of holographic interferometry, which has many significant advantages compared with holographic interferometry double-exposure method and time-average method, but it is not widely used due to some problems in precise reset and film shrinkage. We mainly do some work on accurate reset.
