Abstract

In this paper, based on ambient light sensor and camera sensor, two different receiving methods of visible light signal are experimentally studied. For ambient light sensor, its response time and light intensity are analyzed. The results show that it is available to transmit data with 0.2 kbps data rate over 2 m. For camera sensor, the relationship and difference between original data and corresponding image are studied for the first time. Besides, a series of methods are used to process the original data instead of the image, including data adjustment, histogram equalization and polynomial fitting. Using camera sensor, 2 kbps data rate over 0.3 m transmission with real-time processing of data in mobile phone is achieved even if the stripes are not clear enough, which is faster and more robust. The research is beneficial for practical application of visible light communication (VLC).
