为了解决现有结构光投影系统设备复杂、体积大、成本高，以及相移装置精度要求高、驱动控制电路复杂等一系列技术问题，给出了一种投影和相移的实现方法，并在原理和实验两个方面介绍了该种方法。该方法是通过设计狭缝的宽度及移动狭缝实现相移。实验证明：当狭缝的宽度和移动的距离达到一定要求时，可实现相移；若设置多个相同的狭缝，在增加亮度的同时实现相位的移动。

In order to solve the existing technical problems such as the complex structured light projection system equipment with large volume ,the high cost and high accuracy re-quirements of the phase shift device and the complex drive control circuit etc .,a method to realize the phase shift is proposed .In addition ,this method is introduced in two aspects of principle and experiment .In this method ,phase shifting is achieved through designing the width of the slit and moving the slit .The result of experiments show that phase shifting is a-chieved when the slit width and the slit distance moved reach a certain requirement .If multi-ple same slits are set up ,the phase shifting happens when the brightness increases at the same time .
