400  m rolling-shutter-based optical camera communications link [PDF]

open access: yesOptics Letters, 2020
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.
