Thermally-induced Spectral Variations of LED applied to Optical Multispectral Camera Communications

Abstract

ptical Camera Communication (OCC) appli-cations have intensively risen in recent years. This workproposes using a multispectral or hyperspectral camera asan OCC receiver to take advantage of the high spectralresolution of this type of device with respect to conventionalcameras. Furthermore, spectral features of the LEDs, usuallyused as transmitters in OCC, are affected by temperature.Hence, one of the goals of this work is to benefit from thosespectral variations that will be grasped by the multispectralcamera and thus achieve a new data channel. Therefore,different communication channels could be obtained from asingle light source.
