Voice communication with infrared light 
and fiber optics

Infrared light is very similar to visible light and although it is invisible for human, It is visible and detectable by some animals. Infrared is used in TV remote controls, Cordless keyboards and even in some laptop computers for cordless communication with printers. Devices for transmission of sound via infrared are now available in many electronic stores.
 Project description:
This project investigates the methods and mechanisms of using fiber optics and infrared in transmitting voice. You will perform experiments and make models to demonstrate this technology.
