Non-Line-of-Sight Optical Camera Communication in a Heterogeneous Reflective Background

IEEE Photonics Journal, 2019
In the last few years, optical camera communication (OCC) has benefited from built-in CMOS image sensors in smart devices. OCC is now considered a candidate for incorporation into IEEE 802.15.7r1. A major study on OCC was conducted for line-of-sight (LOS)

Modelization and Characterization of a CMOS Camera as an Optical Real-Time Oscilloscope

IEEE Photonics Journal, 2020
Complementary Metal-Oxide Semiconductor (CMOS) camera sensors are embedded in many consumer electronics products: thanks to the Rolling Shutter (RS) readout mode, they can detect a time-varying light intensity, which is the key to realize Optical Camera ...

Design and construction of a configurable full-field range imaging system for mobile robotic applications [PDF]

, 2011
Mobile robotic devices rely critically on extrospection sensors to determine the range to objects in the robot’s operating environment. This provides the robot with the ability both to navigate safely around obstacles and to map its environment and hence

Motion-Aware Optical Camera Communication With Event Cameras

IEEE Robotics and Automation Letters
As the ubiquity of smart mobile devices continues to rise, Optical Camera Communication systems have gained more attention as a solution for efficient and private data streaming. This system utilizes optical cameras to receive data from digital screens via visible light. Despite their promise, most of them are hindered by dynamic factors such as screen

MIMO Architecture for Optical Camera Communications

The Journal of Korean Institute of Communications and Information Sciences, 2017
Compare with other communication system based RF technology, Optical Camera Communication (OCC) has limitation on data rate due to the low frame rate of camera. The limitation on data rate can be solved with multiple-input and multiple-output (MIMO) technology; and it is the final target of all researches on OCC.

Indoor Positioning Using Deep-Learning-Based Pedestrian Dead Reckoning and Optical Camera Communication

IEEE Access, 2021
The need for an accurate indoor positioning system has rapidly increased with the development of large complex malls and underground spaces. As signals from the global positioning system cannot be received inside buildings, only approximate locations can

Design of light concentrators for Cherenkov telescope observatories

, 2013
The Cherenkov Telescope Array (CTA) will be the largest cosmic gamma ray detector ever built in the world. It will be installed at two different sites in the North and South hemispheres and should be operational for about 30 years.

Laser‐Induced Graphene from Waste Almond Shells

Advanced Functional Materials, EarlyView.
Almond shells, an abundant agricultural by‐product, are repurposed to create a fully bioderived almond shell/chitosan composite (ASC) degradable in soil. ASC is converted into laser‐induced graphene (LIG) by laser scribing and proposed as a substrate for transient electronics.
