Towards Optical Camera Communications Using a Shape-tailored Illuminating Optical Fiber
, 2022 We have recently presented a novel concept of optical camera communications (OCC) based on illuminating optical fibers (IOF) as transmitter (Tx). In this paper, we further investigate this concept of IOF-based OCC system by replacing a straight IOF by an

Optical Fiber Communication Conference (OFC) 2022, 2022
We propose a wide field-of-view (FOV) light-diffusing-fiber (LDF) transmitter optical-camera-communication (OCC). Pixel-row-per-bit-neural-network (PRPB-NN) is employed for rolling-shutter-pattern decoding. PRPB-NN provides efficient decoding at 360o around LDF circumference and 160o Rx rotation-angle at 2100-bit/s.

A Simplified Model for the Rolling Shutter Based Camera in Optical Camera Communications [PDF]
, 2019 A simplified model of the camera for optical camera communications (OCC) based on the rolling shutter effect is proposed and experimentally verified. In OCC, the key parameters are the exposure time, which is proportional to the DC gain and inversely ...

Optical Fiber Communication Conference (OFC) 2021, 2021
We propose and demonstrate using Z-score averaging neural-network (Z-NN) and background-content-removal (BCR) to mitigate the inter-symbol-interference (ISI) in camera-communication (OCC). 950-bit/s over 3-m free-space transmission is achieved.

2021 30th Wireless and Optical Communications Conference (WOCC), 2021
Optical wireless communication (OWC) has received increasing attention recently. One application of OWC uses image sensor as optical receiver, which is known as optical camera communication (OCC). Rolling shutter mode in OCC allows data rate higher than the camera frame-rate operation.
