摘要
En 中文
In this Letter, we develop a novel technique, to the best of our knowledge, to increase the link span (L-s) of a rolling shutter (RS)-based optical camera communications (OCC) system by reducing the spatial bandwidth of the camera in the out-of-focus regions. We demonstrate a 400 m line-of-sight RS-based OCC link, which is to date the longest L-s reported in these systems, and develop a detection method to extract the information out of the video frames, successfully. The proposed system relaxes the condition of a large surface area for the transmitter light source. Consequently, we show that at 400 m L-s and exposure times of 100-80 mu s, a data rate of 450 bps is achieved successfully. (C) 2020 Optical Society of America
