Downlink visible light communication (VLC) using a mobile phone camera is presented. The proposed scheme consists of an 8 $\times$ 8 light-emitting diode (LED) array for data transmission and eight white LEDs for an adequate level of illumination. The white LEDs are also used to acquire camera focus and light metering. Moreover, an efficient rotation compensation feature is provided in the form of...
Vehicle-to-vehicle (V2V) communication using visible light communication (VLC) technology under fog conditions is presented. Fog is known as one of the most detrimental atmospheric conditions that causes outdoor optical wireless communications to be unreliable. The effect of the fog conditions is experimentally analyzed in the VLC-based V2V system. Recognizing the least attenuation coefficient and...
Patient health monitoring technology presents great potential for future healthcare applications and Radio Frequency (RF) communication is the most popular medium for its implementation. This paper presents a static indoor patient monitoring scheme using uplink Visible Light Communication (VLC) suitable for hospital environments. VLC is considered instead of RF communication because of health concerns...
Visible light communication (VLC) has been extensively studied for vehicle-to-vehicle (V2V) communication due to its inherent benefits. The effect of atmospheric turbulence, particularly in rainy condition, on the V2V communication using VLC is examined. The experiments for the V2V communication system was implemented with a modified fixed decision threshold (MFDT) scheme in the presence of rain drops...
An ultrafast laser was used to ablate transparent conducting layers deposited either by multilayered silver and ITO or silver web. Performance of the devices using them as electrodes was examined to confirm the process' efficiency.
Ultrafast laser based materials processing has shown remarkable success in various area of industrial applications. A few examples of innovative applications in displays, OSCs, and other consumer electronics fabrication are demonstrated.
Maximization of the ablation rate of various materials was investigated by optimization of ultrafast laser parameters. The optimized parameters were used to engrave metal roles for micron-sized pattern transfer of conductive ink to flexible substrates.
This paper presents an efficient road surface detection technique based on visible light communication (VLC). It uses light emitting diodes (LED) based car headlamps to illuminate the road surface and capture the diffuse and specular reflections from the road surface. Experiments are conducted indoors to validate its detection scheme and accuracy. Moreover, the proposed VLC based road surface detection...
