Subsea Optics and Imaging (Woodhead Publishing Series in Electronic and Optical Materials)

The use of optical methodology, instrumentation and photonics devices for imaging, vision and optical sensing is of increasing importance in understanding our marine environment. Subsea optics can make an important contribution to the protection and sustainable management of ocean resources and contribute to monitoring the response of marine systems to climate change. This important book provides an authoritative review of key principles, technologies and their applications.The book is divided into three parts. The first part provides a general introduction to the key concepts in subsea optics and imaging, imaging technologies and the development of ocean optics and colour analysis. Part two reviews the use of subsea optics in environmental analysis. An introduction to the concepts of underwater light fields is followed by an overview of coloured dissolved organic matter (CDOM) and an assessment of nutrients in the water column. This section concludes with discussions of the properties of subsea bioluminescence, harmful algal blooms and their impact and finally an outline of optical techniques for studying suspended sediments, turbulence and mixing in the marine environment. Part three reviews subsea optical systems technologies. A general overview of imaging and visualisation using conventional photography and video leads onto advanced techniques like digital holography, laser line-scanning and range-gated imaging as well as their use in controlled observation platforms or global observation networks. This section also outlines techniques like Raman spectroscopy, hyperspectral sensing and imaging, laser Doppler anemometry (LDA) and particle image velocimetry (PIV), optical fibre sensing and LIDAR systems. Finally, a chapter on fluorescence methodologies brings the volume to a close.With its distinguished editor and international team of contributors, Subsea optics and imaging is a standard reference for those researching, developing and using subsea optical technologies as well as environmental scientists and agencies concerned with monitoring the marine environment.* Provides an authoritative review of key principles, technologies and their applications * Outlines the key concepts in subsea optics and imaging, imaging technologies and the development of ocean optics and colour analysis * Reviews the properties of subsea bioluminescence, harmful algal blooms and their impact Content: Cover; Subsea opticsand imaging; Copyright; Contents; Contributor contact details; Woodhead Publishing Series in Electronic and Optical Materials; Preface; Part I Introduction and historic review of subsea optics and imaging; 1 Subsea optics: an introduction; 1.1 Light within aquatic media; 1.2 Fundamentals of marine optics; 1.3 Optical properties of natural waters; 1.4 Optical classification of water bodies; 1.5 Conclusion and future trends; 1.6 Sources of further information and advice; 1.7 References; 2 Subsea imaging and vision: an introduction; 2.1 Introduction. 2.2 A 'potted' and selective history of underwater imaging and vision2.3 Subsea optical imaging; 2.4 Extended range imaging systems; 2.5 Plankton imaging and profiling systems; 2.6 Hybrid systems; 2.7 Future trends; 2.8 Sources of further information and advice; 2.9 References; 3 The history of subsea optics; 3.1 Introduction; 3.2 Exploring the arcane colouring of natural waters; 3.3 Blue reflecting and green transmitting water; 3.4 The principles of Capri's Blue Grotto; 3.5 Historical pieces of laboratory equipment; 3.6 Historical pieces of field equipment; 3.7 Ocean colour comparator scales. 3.8 Conclusion3.9 Remarkable notes and thoughts; 3.10 References; Part II Biogeochemical optics in the environment; 4 Measurement of hyperspectral underwater light fields; 4.1 Hyperspectral versus multispectral radiometry; 4.2 Radiometry fundamentals; 4.3 Sensor design and collector geometry; 4.4 Spectral resolution, noise levels and temporal response; 4.5 Radiometer calibration and deployment; 4.6 Hyperspectral characteristics of natural waters; 4.7 Significance of transpectral processes; 4.8 Conclusion and future trends; 4.9 References; 5 Colored dissolved organic matter in seawater. 5.1 Introduction5.2 Optical properties of CDOM; 5.3 Measurement of CDOM; 5.4 Applications of CDOM measurement in the ocean; 5.5 Future trends; 5.6 Sources of further information and advice; 5.7 References; 6 Optical assessment of nutrients in seawater; 6.1 Introduction; 6.2 Direct optical measurement; 6.3 Indirect optical measurement; 6.4 Conclusion and future trends; 6.5 References; 7 Bioluminescence in the sea; 7.1 Introduction; 7.2 Measurement of bioluminescence in the ocean; 7.3 Propagation of bioluminescence in and out of the ocean; 7.4 Future trends; 7.5 Acknowledgements; 7.6 References. 8 Optical assessment of harmful algal blooms (HABs)8.1 Introduction: addressing the diversity of harmful algal blooms; 8.2 Algal features for bio-optical assessment; 8.3 Scale and resolution in surveillance of algal blooms; 8.4 Emerging advancement in bio-optical sensor technologies; 8.5 Transfer to operational oceanography; 8.6 References; 9 Optical techniques in studying suspended sediments, turbulence and mixing in marine environments; 9.1 Introduction; 9.2 Particles in seawater: their mass, density and settling speed; 9.3 Particle size distributions; 9.4 Particles and turbulence.
