Laser Scanning devices (LADAR for Laser Detection and Ranging) are
used in construction projects to capture as-built data. They can
rapidly generate large unstructured point clouds. This study
describes an experiment in which an I-beam on a concrete floor
surface is scanned, and the resulting point cloud data used to
calculate its pose. Two approaches for segmenting potential target
objects are described. Principal axis analysis is used to determine
the pose of the I-beam. Bounding boxes are then formed around it
and compared to an ideal bounding box generated from the known
geometric specifications of the I-beam of interest. A separate
laserbased site measurement system (SMS) was used to measure points
on the Ibeams to form reference data for estimating the closeness
of fit of computed pose of the I-beam to measured pose of the
I-beam. Three spheres were used as a means of registering the scan
and SMS axes.
The processing of signals or data is one of the cores of the
information chain from production to application. More and more
signals should be processed digitally in the big data era. Rapid
and massive advances in digital signal processing (DSP) technology
have been achieved over the past several decades. DSP technology
revolutionized the electronics and opto-electronics industries. DSP
technology is almost an all-embracing field and is advancing with
each passing day. The classical application areas of DSP such as
telecommunications, speech and image processing continue to be the
main contributor to its growth. This book compiles cutting-edge
research in several elementary and advanced topics in DSP, focusing
on areas such as filter design algorithms, hardware/software
techniques, and their applications. This book has a special
emphasis on the modeling and design of optical communication
filters. Use of well-developed DSP techniques and algorithms to
design the wavelength division multiplexing (WDM) devices is a wise
use of existing technology. The authors also share several of their
thoughts concerning the practical DSP systems. The DSP theory and
hardware for obscured object identification, and its applications
in the intelligent baggage scanners are introduced systematically.
This book will be helpful for students, researchers and engineers
in the DSP fields to understand the basic knowledge and techniques
of software, hardware, devices, and systems.
This book provides detailed and current information on using
fullerenes (bucky-balls) in photodynamic therapy (PDT), one of the
most actively studied applications of photonic science in
healthcare. This will serve as a useful source for researchers
working in photomedicine and nanomedicine, especially those who are
investigating PDT for cancer treatment and infectious disease
treatment. The book runs the gamut from an introduction to the
history and chemistry of fullerenes and some basic photochemistry,
to the application of fullerenes as photosensitizers for cancer and
antimicrobial inactivation.
Pathogens such as viruses and bacteria are among the greatest
threats to human health worldwide. In today's era of population
growth and international travel, new technologies are desperately
needed to combat the spread of known and emerging pathogens. This
book presents a new concept for pathogen inactivation called
selective photonic disinfection (SEPHODIS). The SEPHODIS technology
inactivates pathogens by mechanical means, a total paradigm shift
from traditional chemical and physical methods. The unique strength
of SEPHODIS resides in its capability to inactivate pathogens while
preserving desirable materials such as human cells and proteins.
The technology also avoids the need to use chemicals, drastically
reducing the risk of side effects. These properties make SEPHODIS
ideal for important biomedical applications such as safeguarding
blood products and therapeutics against pathogens, as well as
producing effective and safe vaccines to combat infectious disease.
Written in a style that is both technically informative and easy to
comprehend for the layman reader, this book illustrates the story
of SEPHODIS from its initial discovery and bench studies to its
real-world applications.
Rolf T. Borlinghaus erlautert die Ursachen fur die klassische
Begrenzung der Lichtmikroskopie und beleuchtet die neuen
Super-Hochaufloesungstechniken. Dies ist besonders aktuell, da der
Nobelpreis 2014 fur Chemie fur die Entwicklung von Technologien
vergeben wurde, die es nun ermoeglichen, mit Lichtmikroskopen
feinere Details aufzuloesen, als es die klassische Theorie
einschrankend vorhersagt. Diese neuen Methoden stellen aber nicht
das bisherige Weltbild der Optik in Frage, vielmehr nutzen sie ganz
andere Phanomene, um mittels klassischer Optik
Positionsbestimmungen von Molekulen durchzufuhren. Das ist
theoretisch beliebig genau moeglich.
Materials and Reliability Handbook for Semiconductor Optical and
Electron Devices provides comprehensive coverage of reliability
procedures and approaches for electron and photonic devices. These
include lasers and high speed electronics used in cell phones,
satellites, data transmission systems and displays. Lifetime
predictions for compound semiconductor devices are notoriously
inaccurate due to the absence of standard protocols. Manufacturers
have relied on extrapolation back to room temperature of
accelerated testing at elevated temperature. This technique fails
for scaled, high current density devices. Device failure is driven
by electric field or current mechanisms or low activation energy
processes that are masked by other mechanisms at high temperature.
The Handbook addresses reliability engineering for III-V devices,
including materials and electrical characterization, reliability
testing, and electronic characterization. These are used to develop
new simulation technologies for device operation and reliability,
which allow accurate prediction of reliability as well as the
design specifically for improved reliability. The Handbook
emphasizes physical mechanisms rather than an electrical definition
of reliability. Accelerated aging is useful only if the failure
mechanism is known. The Handbook also focuses on voltage and
current acceleration stress mechanisms.
Optical Spectroscopy is an interdisciplinary science dedicated to
generating and building knowledge in the field of spectroscopy and
as a tool for practical investigations. This book has been
elaborated for the use of specialists, students and young
scientists interested in material characterization and direct
investigation of various technological processes. As the title
shows, the project of this book is ambitious and challenging. The
topics have been selected to supply the physical background needed
to understand the main spectroscopic principles and, at the same
time, to reveal new potentiality for applications. Subjects like
Reflectance Spectroscopy, Infrared Attenuated Total Reflection or
Photoreflectance Spectroscopy provide an overview of classical
methods in spectroscopy in contexts of new applications and reveal
possibilities in new domains such as medicine, environmental
investigations, etc. Various spectroscopic measurement methods
embedded in characterization of materials, devices or technological
processes are extensively presented.

This book considers some general laser-induced processes that are
involved in laser-matter interactions. A brief review is presented
about a very interesting application of laser beams in the fields
of materials science: the growth of zinc oxide (ZnO) nanostructured
films by Pulsed Laser Deposition (PLD). In addition, safe and
precise cavity detection, especially of dangerous or inaccessible
voids, is essential to safe production in a working mine. The
advantages and disadvantages of laser detection systems are
analysed, and a combination of laser scanning techniques and
conventional survey methodology is proposed. Other chapters in this
book present an overview on laser cladding, a discussion of the
applications of structured laser beams in laser refractography
technology, a review of some fundamentals of laser-induced
breakdown spectroscopy (LIBS) and an analysis of laser forming of
steel parts by means of diode lasers.

Lasers are an interesting option as a light source for projection
displays, because of their high directivity. As a result, a high
brightness light source with a small beam profile, a good beam
quality and good collimation characteristics is obtained. This
allows the application of small light engines and display panels
without loosing much intensity. As a result, a small and quite
cheap projector can be gained. If the panel costs are still too
high, laser sources can also be used to realize even cheaper
architectures that use 1D display modules or a flying spot scanner.
Additionally, the laser beam is highly monochromatic, so a
projection unit using three primaries can cover a large colour
gamut. The intention of this book is to give an overview on state
of the art projection techniques, applicable laser sources and
challenges in setting up micro- or even high power laser front
projection systems.
Ultrashort Laser Pulse Phenomena serves as an introduction to the
phenomena of ultrashort laser pulses and describes how this
technology can be applied in areas such as spectroscopy, medical
imaging, electromagnetism, optics, and quantum physics. Combining
the principles with experimental techniques, the book serves as a
guide to designing and constructing femtosecond systems.
The second edition has updated and expanded its content, and
includes more examples of ultrashort sources and a more
comprehensive fundamentals chapter. Diagnostic techniques and
applications involving sensors, mode-locked lasers, and imaging
have been fully revised to include current technologies.
Written in a tutorial style, this book is suitable for senior
undergraduate and graduate students as well as engineers and
scientists working in the areas of optics, spectroscopy, optical
imaging, photochemistry, and ultrafast science and engineering.
*Provides an easy to follow guide through "faster than electronics"
probing and detection methods
*THE manual on designing and constructing femtosecond systems and
experiments
*Discusses essential technology for applications in
micro-machining, femtochemistry, and medical imaging
One of the first texts to offer a simple presentation of the
theoretical foundations of steady-state laser spectroscopy, this
volume is geared toward beginning theorists and experimentalists.
It assists students in applying theoretical ideas to actual
calculations in laser spectroscopy with a systematic series of
examples and exercises. Starting at an elementary level, students
gradually build up their practical skills with demonstrations of
how simplified theoretical models relate to experimentally
observable quantities. Detailed derivations offer students the
opportunity to work out all results for themselves.
The first chapter introduces background material on electrodynamics
and quantum mechanics, with an emphasis on the density matrix, its
equation of motion, and its interpretation. Chapter 2 derives the
response of the medium to strong fields. After mastering these two
parts, students can proceed to later chapters in any order they
wish. Succeeding chapters cover the physical basis of laser
operation, applications central to laser spectroscopy, the
inclusion of laser fluctuations into the theory, and field
quantization. Numerous references, which appear in separate
sections, form a concise history of the field and its most
noteworthy developments.
