多功能X—Y步进器由电子装置控制机械装置携带全息干板或测试头作X、Y两个方向的一维或二维步进移动,能够用于多种全息实验中,使实验操作方便,精度得到提高。本文介绍X—Y步进器的功能及参数,并对其主要用途的实验方法加以说明,还给出一部份实验的结果。 The multi-function X-Y stepper is controlled by the electronic device. The holographic dry plate or the test head carries the one-dimensional or two-dimensional step movement in X and Y directions and can be used in various holographic experiments to make the experimental operation Convenient, precision is improved. This article introduces the functions and parameters of the X-Y stepper, and describes the experimental methods for its primary use. It also gives the results of some experiments.
