解説
This book provides insight into an unconventional modality of imaging where several spectral images are captured by a single snapshot under multi-laser illumination, ensuring high-speed imaging within extremely narrow spectral bands. This method has three distinct advantages, if compared to common commercial multispectral imaging systems - considerably improved spectral selectivity (or colour sensitivity) of imaging, avoided motion artefacts in the spectral image sets, and simpler/faster image processing as integrals over the spectral bands of imaging are replaced by numbers of the fixed working wavelengths.
The basic principles and progress in this field are reviewed, focusing on applications for human skin diagnostics and printed forgery detection. The designs of ten different lab-developed prototypes that implement this method are described, along with results of their laboratory, clinical and/or forensic tests. This research leads to the development of new equipment and protocols for better skin diagnostics and the advanced detection of money, document, and artwork forgeries.
Chapter 1 explains the basics of spectral imaging, including the main principles of multispectral and hyperspectral imaging. Chapter 2 introduces the snapshot multi-spectral-line imaging (SMSLI) method, focusing on lasers as multi-wavelength illumination sources. Chapter 3 describes multi-laser illumination designs while Chapter 4 presents main specifications of the lab-assembled prototype devices implementing such designs. Results of the test measurements confirming applicability of the developed solutions for analysis/mapping of colour pigments in clinical diagnostics and forgery detection are discussed in Chapters 5 and 6, respectively.
This will be a valuable reference for laser and imaging professionals, photonics researchers and engineers, clinicians (dermatologists, plastic surgeons, oncologists), forensic experts, and students of physics, chemistry, biology, medicine, and engineering.
