closed loop

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

虚拟触觉是一个触觉信息循环反馈的闭环,中包含着虚拟环境与现实环境两者间双向的信息传递。

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、扰的特点，不仅适用于平行直线型条纹图像，而且对含闭合条纹的复杂涉图像同样适用。
