摘要
针对实时全息干涉计量的特点,结合相移位相测量技术,提出一种利用物体本身变化产生的位相变化来实现实时全息干涉计量中时间序列条纹位相的测量方法,通过分析得到不同时刻位相变化及整个变化过程中位相累计变化的计算公式.
Abstract
In real-time holographic interferometry, the phase measurement of the time-sequence interference fringes is very important. On the theoretic analysis, this paper proposes a novel phase measurement method by use of the phase variation of the object light wave and the phase-shifting technique, and obtains the calculational formula of phase variation in whole process.
