| Abstract: | By applying advanced technology, we improve the traditional single-slit diffraction experiment. Due to adopting Single Chip Processor (SCP),both the sampling of experiment data and the output of experiment results can be automatically carried out. The use of photosensitive array makes it possible to obtain the distribution of diffracted light intensity with only one sampling. Errors caused by repeated sampling in traditional instrument are removed, which shall greatly raise the experimental precision. |
