Optical camera communications using dynamic vision sensor: A practical assessment

Abstract

The "Silicon Retinas"or "Event Cameras"are bio-inspired technologies that revolutionize the acquisition of visual information by mimicking the neural architecture of the eye. These cameras respond asynchronously to changes in scene illumination at the pixel level, providing high-precision time information and low latency in the order of microseconds. In this work, we evaluate the capabilities of the DVS camera for various transmitter and receiver parameters. The results showed that, apart from the refractory period, which is the main limiting parameter in optical camera links, the performance of the optical communication system increases with lower offset irradiance values.
