VOICE VIA LIGHT
"A Specially Designed Optical Communication Kit for All Educational Levels"

This "Voice Via Light" is a specially designed optics/photonics kit suitable for students at all levels who want to learn the way to send data such as sound via light. This "Voice Via Light" is designed so that both "Free Space" and "Fiber Optic" communication schemes can be easily demonstrated. In addition, this specially designed educational kit can be used to check whether or not the interesting light source has the voice signal that we can hear in it. Furthermore, it can be used to study the fundamentals of optics/photonics such as reflection, refraction, total internal reflection, polarization, diffraction, and the propagation of light in the optical fiber.

Fig.1 shows "Voice Via Light"

Our "Voice Via Light" consists of a light transmitter, a light receiver, an optical fiber, a mono cable, and a specially written manual that covers fundamentals of optics and related demonstrations using "Voice Via Light" Kit in a compact portable transparent plastic box suitable for indoor and outdoor demonstrations.

Examples demonstrating light refraction, light total internal refraction, and the propagation of light in an optical fiber are shown below, respectively.
