| Abstract: | According to the characteristics of single slit diffraction, calculation method of the relative intensity of central bright fringe for single slit diffraction based on CCD technology is proposed. The fringe pattern of single slit diffraction is obtained by using CCD and the corresponding software. By analyzing the converted statistical data, intensity distribution curves and the corresponding data, with the aid of origin pro. v7.5 drawing software, the relative intensity of＇ central bright fringe is obtained. |
