Smartphone Camera Based Visible Light Communication

Indoor Localization Based on Visible Light Communication

Visible Light Communication

The visible light communication (VLC) refers to the communication technology which utilizes the visible light source as a signal transmitter, the air as a transmission medium, and the appropriate photodiode as a signal receiving component. The visible light communication technology has a short history compared with other communication technology, for example, public old telephone service, Ether...

Seeing elements by visible-light digital camera

A visible-light digital camera is used for taking ordinary photos, but with new operational procedures it can measure the photon energy in the X-ray wavelength region and therefore see chemical elements. This report describes how one can observe X-rays by means of such an ordinary camera - The front cover of the camera is replaced by an opaque X-ray window to block visible light and to allow X-...

Software Defined Visible Light Communication

Software Defined Radio (SDR) has proven to be a practical and effective tool in RF communications, allowing flexible and rapid exploration of dynamic RF signal processing techniques while accelerating advancement of configurable RF antennas and front-end hardware. SDR concepts can be adapted to other physical media; we investigate a Software Defined Visible Light Communications (SDVLC) solution...

High - speed visible light communication system based on SiPM

Silicon Photomultiplier (SiPM) is a photodetector with very high sensitivity, fast response and good performance in oversaturation conditions. When SiPM faces incident optical radiation (sometimes imperceptible for other photodetectors) is able to detect very small variations of light. In this work, we present a SiPM-based optical receiver ables to discriminate small light signals from backgrou...
