Development and Application of Light-Field Cameras in Fluid Measurements


Book Description

This book provides a comprehensive guide to 3D Light-Field camera based imaging, exploring the working principles, developments and its applications in fluid mechanics and aerodynamics measurements. It begins by discussing the fundamentals of Light-Field imaging and theoretical resolution analysis, before touching upon the detailed optics design and micro-lens array assembly. Subsequently, Light-Field calibration methods that compensate for optical distortions and establish the relations between the image and real-word 3D coordinates are covered. This is followed by Light-Field 3D reconstruction algorithms which are elaborated for micrometer-scale particles and centimeter-scale physical models. Last but not least, implementations of the preceding procedures to selected fundamental and applied flow measurement scenarios are provided at the end of the book. Development and Application of Light-Field Cameras in Fluid Measurements gives an in-depth analysis of each topic discussed, making it ideal as both an introductory and reference guide for researchers and postgraduates interested in 3D flow measurements.

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.

Imaging Measurement Methods for Flow Analysis


Book Description

In 2003 the German Research Foundation established a new priority programme on the subject of “Imaging Measurement Methods for Flow Analysis” (SPP 1147). This research programme was based on the fact that experimental ?ow analysis, in addition to theory and numerics, has always played a predominant part both in ?ow research and in other areas of industrial practice. At the time, however, c- parisons with numerical tools (such as Computational Fluid Dynamics), which were increasingly used in research and practical applications, soon made it clear that there are relatively few experimental procedures which can keep up with state-of-the-art numerical methods in respect of their informative value, e.g. with regard to visu- spatial analysis or the dynamics of ?ow ?elds. The priority programme “Imaging Measurement Methods for Flow Analysis” was to help close this development gap. Hence the project was to focus on the investigation of ef?cient measurement me- ods to analyse complex spatial ?ow ?elds. Speci?c cooperations with computer sciences and especially measurement physics were to advance ?ow measurement techniques to a widely renowned key technology, exceeding the classical ?elds of ?uid mechanics by a long chalk.

Particle Image Velocimetry


Book Description

Particle image velocimetry, or PIV, refers to a class of methods used in experimental fluid mechanics to determine instantaneous fields of the vector velocity by measuring the displacements of numerous fine particles that accurately follow the motion of the fluid. Although the concept of measuring particle displacements is simple in essence, the factors that need to be addressed to design and implement PIV systems that achieve reliable, accurate, and fast measurements and to interpret the results are surprisingly numerous. The aim of this book is to analyze and explain them comprehensively.
