Abstract: With the increasing popularity of solid state lighting devices, Visible Light Communication (VLC) is globally recognized as an advanced and promising technology to realize short-range, high speed as well as large capacity wireless data transmission. Before using visible light communication to a large extend, it is important that one should have the basic knowledge about parameters of visible light and how the parameters are different from IR. The low cost optical test bench contains systems for measuring parameters of light such as intensity and dispersion. Also the test bench includes a practical audio transmitter system which uses visible light as the transmission medium.

Keywords: Optical Test bench; Photo goniometer; VLC; Intensity; Dispersion.
