【Abstract】 The design of a new detecting instrument for moiré 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 moiré fringe. This paper primarily focuses on the structure and the measuring theory of the instrument. The moved number of moiré fringe which is caused by relative shift of the gratings is nice, and the width of moiré fringe which is caused by the bias angel of the gratings is verified to closely consistent with theoretical result.更多还原
