摘　　要：介绍一种应用CCD进行测量的光栅莫尔条纹特性检测仪.该检测仪的结构完全开放,检测过程透明.不仅能够检测光栅副相对移动位移和移动方向与莫尔条纹移动数目和移动方向的关系,而且可以检测光栅副夹角变化对莫尔条纹宽度的影响.应用该仪器可以进行"莫尔条纹移动数目与光栅副移动位移关系测定"和"光栅副夹角变化和莫尔条纹宽度变化关系测定"两个实验,实验结果理想.The design of a new detecting instrument for moire fringe speciality by using CCD is introduced. The structure of the new instrument is completely open and the process of detecting is intuitionistic. This instrument can be used to detect all the characteristics of moire fringe. This paper primarily focuses on the structure and the measuring theory of the instrument. The moved number of moire fringe which is caused by relative shift of the gratings is nice, and the width of molte fringe which is caused by the bias angel of the gratings is verified to closely consistent with theoretical result.
