closed-loop

Virtual haptical system is a circulate feedback closed loop, including bidirectional information transfer between virtual and really environment.

虚拟触觉系统是一个触觉信息循环反馈的环系统,其中包含着虚拟环境与现实环境两者之间双向的信息传递。

It has been proved that this method is fit for the parallel linable fringes and the interferograms with the arbitrary closed loop fringe pattern.

该方法具有精度高、抗干扰的特点，不仅适用于平型条纹图像，而且对含合条纹的复杂干涉图像同样适用。
