摘要

The visible and infrared light bands in the optical spectrum have become an interesting topic in communications. Optical camera communication is a type of visible light communication that uses image sensors rather than individual photodiodes to receive data. An optical camera is a complementary technology to wireless communications via light, as camera devices can be used in smart devices such as tablets and smartphones. An optical camera makes use of an image sensor or camera in areas such as intelligent transportation, vehicle communication, indoor positioning, and the Internet of Things in indoor and outdoor applications. In this paper, we present an analysis of the OCC technology leveraging the rolling shutter mechanism of smartphone cameras. Further, we demonstrate an OCC system experimentally. The experimental OCC system operates by controlling an RGB LED as a VLC transmitter using an FSOOK modulation and receiving captured video frames by a smartphone camera at 20 and 50 cm communication distances. The results show the rolling shutter effect of the camera used as a receiver. Also, they show that the stripe width is affected by various parameters such as the communication distance and modulation frequency. The experimental evaluation reveals a better SNR at an exposure time of 4000 ms through expanded distances from 10 to 50 cm.
