An Effective Design of a Remote-Controlled System for Online Studying Light Diffraction ExperimentPages 646-469
Huynh-Tuan-Anh Nguyen Abstract:
We proposed and demonstrated a design of a remote-controlled system for studying the phenomenon of light diffraction. The design of the system and its working principle are described in detail. A website is built where all the commands are possibly conducted through built-in buttons. The laser switching on or off, and the selection of the type of grating can be controlled remotely through the internet connection while their images are observable by the camera. The diffraction pattern is observed through the camera. The system works well for a demo using two types of diffraction grating of 80 lines/mm, and 100 lines/mm. The obtained result is not only meaningful in building up an online laboratory but also in the development of the field of Education Science and Technology.
