| Abstract: | The function and the implementation method of a demonstration device of Fraunhofer diffraction has been introduced. The device is made of laser source,slit set,detector,liquid crystal display,computer,single chip processor and stepping motor. By designing software on single chip processor and PC,the demonstration function could be realized. The device could demonstrate Fraunhofer diffraction independently or through computer control. |
| Keywords: | Fraunhofer diffraction single chip distributed intensity |
