摘要
将载波技术应用到数字相移法中,利用双折射特性,将有用信息加到一线性载波中,再通过解调算法处理,实现从一幅相移图中分离相位,并给出实验例证。
In this paper.the birefraction carrier wave phase-shifting technique is proposed using the initial birefraction pattern as carrier. The image's distinguishing only depends on one picture. As an example, an experiment has been given.
