Digital Holography: Applications and Emerging Technologies


Book Description

With the rapid growth of computing and display technologies, digital holography (DH) has undergone significant advancement in the past two decades. Contemporary research works have enabled holography, a technology which is originally intended for displaying three-dimensional (3-D) images, to be deployed in numerous scientific, engineering, and bio-medical applications. Notably, digital holography has been incorporated into quite a number of contemporary applications, such as, but limited to holographic cryptography, optical metrology, remote sensing and inspection, and more recently, quantum computing. The success attained with DH so far does not limit its development to its current state-of-the-art, but rather research on holography keeps on expanding, with new ideas and methods keep coming up in a sustainable manner. This Research Topic aims to collect representative works from experts in the field, with the aim of providing an insight on the overall picture on digital holography, as well as reporting existing methodologies and emerging technologies that are likely to have strong impact on future research directions. Participating in the Research Topic, either as authors or readers, also facilitates establishing a platform for researchers to network, and to share their knowledge.

Laser Radar


Book Description

In today's world, the range of technologies with the potential to threaten the security of U.S. military forces is extremely broad. These include developments in explosive materials, sensors, control systems, robotics, satellite systems, and computing power, to name just a few. Such technologies have not only enhanced the capabilities of U.S. military forces, but also offer enhanced offensive capabilities to potential adversaries - either directly through the development of more sophisticated weapons, or more indirectly through opportunities for interrupting the function of defensive U.S. military systems. Passive and active electro-optical (EO) sensing technologies are prime examples. Laser Radar considers the potential of active EO technologies to create surprise; i.e., systems that use a source of visible or infrared light to interrogate a target in combination with sensitive detectors and processors to analyze the returned light. The addition of an interrogating light source to the system adds rich new phenomenologies that enable new capabilities to be explored. This report evaluates the fundamental, physical limits to active EO sensor technologies with potential military utility; identifies key technologies that may help overcome the impediments within a 5-10 year timeframe; considers the pros and cons of implementing each existing or emerging technology; and evaluates the potential uses of active EO sensing technologies, including 3D mapping and multi-discriminate laser radar technologies.

Metasurface Holography


Book Description

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.
