Smartphone beam profile in a screen-to-camera-based optical communication system

Abstract

This paper presents an experimental investigation of a screen-to-camera-based communication (S2C) system. The study examines the performance of the smartphone transmitter (Tx) screen in terms of power received, beam profile, and Lambertian order as well as evaluates the impact of different transmission conditions such as distance, tilt, and rotation angles. The results demonstrate that for the line of sight (LOS) link, the Tx has an average Lambertian order of 3.5 and a transmission accuracy of over 100%. Overall, the study demonstrates the potential of optical camera communication technology for the development of efficient and reliable S2C systems.
