Download or read book MEMS Mirrors written by Huikai Xie (Ed.) and published by . This book was released on 2018 with total page 210 pages. Available in PDF, EPUB and Kindle. Book excerpt: MEMS mirrors can steer, modulate and switch light, as well as control the wavefront for focusing or phase modulation. MEMS mirrors have found enormous commercial success in projectors, displays and fiberoptic communications. Micro-spectrometers based on MEMS mirrors are starting to appear in the consumer market. There are also many breakthroughs in applying MEMS mirrors for endoscopic imaging. Equally excitingly, a new wave of opportunities for MEMS mirrors is coming up, for example, micro-LiDAR for autonomous driving and robotics, optical cross connect (OXC) for cloud data centers, and optical scanners for virtual reality/augumented reality, just to name a few. Of course, there are a number of big challenges that researchers and engineers must overcome to fully utiltize MEMS mirrors' potential: modeling and control are inherently complex due to the multiphysics, multi-DOF and nonlinear nature of the microactuators for MEMS mirrors; reliability is always a huge hurdle for commercilization; and the tradeoffs among the speed, aperture, and scan range are often overwhelming. Accordingly, this Special Issue seeks to showcase research papers, short communications, and review articles that focus on: (1) novel designs, fabrication, control, and modeling of MEMS mirrors based on all kinds of actuation mechanisms; and (2) new developments of applying MEMS mirrors of any kind in consumer electronics, optical communications, industry, medicine, agriculture, space, or defense.

Download or read book Unsettled Topics Concerning Coating Detection by LiDAR in Autonomous Vehicles written by Cristina Porcel Magnusson and published by SAE International. This book was released on 2021-01-18 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: Autonomous vehicles (AVs) utilize multiple devices, like high-resolution cameras and radar sensors, to interpret the driving environment and achieve full autonomy. One of these instruments—the light detection and ranging (LiDAR) sensor—functions like radar, but utilizes pulsed infrared (IR) light, typically at wavelengths of 905 nm or 1,550 nm. The LiDAR sensor receives the reflected light from objects and calculates each object’s distance and position. In current vehicles, the exterior automotive paint system covers an area larger than any other exterior material. Therefore, understanding how LiDAR wavelengths interact with other vehicles’ coatings is extremely important for the safety of future automated driving technologies. Some coatings are more easily detected by LiDAR than others. In general, dark colors can absorb as much as 95% of the incident LiDAR intensity, reducing the amount of signal reflected toward the sensor. White cars are more easily detected as they exhibit high IR reflectivity. Many other factors like gloss level, effect pigments, and refinishes can affect reflectivity and even blind LiDAR sensors. On the other hand, several variables define overall LiDAR and perception system performance, including IR reflectivity of paint but also the target object’s geometry, the type of LiDAR technology employed, angle of the target surface, environmental conditions, and sensor fusion software architecture. Sensing Technologies and Materials are two different industries that have not directly interacted in the perception and system sense. With the new applications in the AV industry, approaches need to be taken in a multidisciplinary way to ensure a reliable and safe technology for the future. This report provides a transversal view of the different industry segments from pigment and coating manufacturers to LiDAR component and vehicle system development and integration, and a structured decomposition of the different variables and technologies involved.

Download or read book Nanorobotics written by Vic Lynn & Kit Cooley and published by Scientific e-Resources. This book was released on 2018-01-21 with total page 343 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the 1980s and 1990s, a handful of authors began speculating about the physical forms that future medical nanorobots might take. A few created artist's conceptions of their devices. During this time, only the broadest analyses of the missions and capabilities that might be desired had been attempted. Detailed technical and engineering studies, in many cases, still lay years in the future. Despite this handicap, some of these designs have many plausible elements, along with other elements which, in hindsight, may appear fanciful, impractical, or even dangerous. These speculations continue through the present. The science of nanorobotics plays a vital role in the development of robots, whose structure is built by using nanoscale components and objects. The nature of the components being in the nano scale allows the researchers for the engineering of the mimic of human beings. The construction of the various complex parts, which constitute the robots have been possible due to nanorobotics. Nanobots, nanites, nanoids or nanomites are some of the hypothetical devices created with the knowledge of nanorobotics. Nanorobotics will set new standards in pharmaceuticals, cosmetics, aerospace and automotive industries, security, defense, environmental protection, electronics, computers and communications. Within the next two decades, we may have tiny machines inside us, combatting every disease known to humankind and slowing down, even reversing the aging process, making us practically immortal. This book describes how to build a mobile computer user a citizen of the Internet and how to admittance everything the in sequence superhighway has to present. The objective of this book is to make available you with an opening to the design and completion of Internet protocols that are helpful for maintaining network connections still while moving from place to position.

Download or read book Metasurface Holography written by Zi-Lan Deng and published by Springer Nature. This book was released on 2022-05-31 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: The merging of metasurface and holography brings about unprecedented opportunities for versatile manipulation of light in terms of both far-field wavefront and near-field profile. In this book, a brief evolving history from surface plasmon polariton holography to metamaterial holography and finally to metasurface holography is introduced at first. Basic physical mechanisms that govern the phase modulation rules behind metasurface holography design are discussed later. Next, extended functionalities such as arbitrary polarization holography, vectorial holography, full-color holography, and hybrid holography achieved in the metasurface platform are presented. Surface wave and metagrating holography that bridges the on-chip surface wave and free-space wave is also introduced. In the end, we envisage practical applications of high-fidelity 3D holographic display, high-secure encryption, and high capacity digital encoding and also indicate remaining challenges based on metasurface holography.
