摘　　要：This paper explains the Moire chromatography technique and the optical characteristics when the light crosses the 3D air flow field.Based on this,taking grating,CCD camera,optical filter and diaphragm as the main device,a multi-direction Moire chromatography optical system was designed.The system consists of five detective light paths,in each detective light path there is parallel and same periodic grating and filtering minipore placed on the lens’focal length plane;the grating is used to adjust the space length and angle between the two gratings,and the filtering minipore is used to remove the unorderly high frequency intermix in the Moire fringe.Utilizing the computer escalator method to convert the tested value,the vivid interference fringe of tested parameter can be obtained.The application of this system in precision measurement and medicine is also analyzed and discussed.
