| Abstract: | A simple and easy-buildup light equipment is designed. It can collect the data and output the curve real-timely by computer and demonstrate the distribution of light intensity of the Fresnel straight edge diffraction. It has the advantages of easy operation, clarity and precision, and so on. |
