Light by Kimberly Arcand,Megan Watzke Pdf

A stunning visual exploration of the power and behavior of light across the entire electromagnetic spectrum. Light allows humans to see things around us, but we can only see a sliver of all the light in the universe, also known as the electromagnetic spectrum. Renowned science communicators Kim Arcand and Megan Watzke bring the entire spectrum to life and present the subject of light as never before. Organized along the order of the electromagnetic spectrum--from Radio waves to Gamma rays--each chapter focuses on a different type of light. From ultraviolet light, used in microscopy to image plant cells and bacteria, to X-rays, which let us peer inside the human body and view areas around black holes in deep space, Arcand and Watzke show us all the important ways light impacts us. With hundreds of stunning full-color photographs, including new images from the James Webb Space Telescope, Light is a joy to read and browse.

Visible Light Communication and Positioning by Chen Gong Pdf

In recent years, wireless communications have significantly evolved due to the advanced technology of smartphones;, portable devices; and the rapid growth of Internet of Things, e-Health, and intelligent transportation systems . Moreover, there is anare increasing need fors of emerging intelligent services like positioning and sensing in athe future intelligence society. Recent years have witnessed the growing research interests and activities in the communication and intelligencet services in the optical wireless spectrum, as a complementary technology to more established radio frequency (RF)-based systems, to overcome the spectrum sparsity and increases data rates in crowded locations, due to the limited transmission range and interference. The OWC technology offers advantages such as free license, wide bandwidth, inherent security, no RF electromagnetic interference, and immunity to electromagnetic interference. The attractive applications of the optical spectrum include ultra-violet tactic communication, blue/green underwater communication, visible light positioning, and vehicular communication/sensing in intelligent transportation systems. The present Iissue, as named "Visible Light Communication and Positioning", focuses on visible light communication and visible light positioning, where four papers are on visible light communication and three papers are on visible light positioning. For visible light communication, the published works focus on the devices, the physical-layer techniques, and the system work aspects. Besides VLC, visible light positioning works include fingerprint-based indoor positioning system for multiple reflections, the impact of LED tilt on visible light positioning accuracy, and a mobile optoelectronic tracking system based on feedforward control.

Visible Light Communication Based Indoor Localization by Mohsen Kavehrad,Reza Aminikashani Pdf

This book demonstrates the research on VLC based indoor localization in four aspects: first, it constructs the concept and model of the system; second, positioning algorithms, as the main issue in indoor localization, are detailed; third, many approaches are proposed to further improve the positioning performance; fourth, challenges will be detailed. Impulse response with multipath reflections are analyzed. Orthogonal frequency division multiplexing (OFDM) is proposed, and positioning performance is largely improved compared to On-off-keying (OOK) modulation. The readers will get a broad view of VLC based indoor localization from the background to the future challenges.
