This book describes all optical properties of wooden materials, including definitions and measurement methods of optical parameters such as absorbance, diffuse and specular reflectance, colour and gloss. Basic knowledge regarding the reflectance measurement in the ultraviolet, visible, near- and middle infrared radiation ranges is also discussed. It examines conducting correct optical measurements, as well as introduces the validity limits of the individual methods. Steaming as an environmental-friendly colour modification process is introduced by the description of the steaming properties of eight species. Steaming schedules for wood-working industry are suggested to create optimum colour modification. Natural and artificial aspects of photodegradation are monitored by studying the colour change and using infrared reflectance spectrum measurement. The effect of influencing parameters such as temperature, relative air humidity and leaching effect of rain is also discussed. Combined effects of heat and light on the optical properties of wood in all possible combinations are presented. The book helps wood researchers and Ph.D. students perform correct and repeatable optical measurements and evaluations in order to draw the right conclusions.

This book presents recent advances in three-dimensional (3D) imaging and display frameworks, encompassing three categories of 3D imaging and display technologies. The first category is nonphotorealistic 3D approaches based on conventional optical cameras to implement 3D stereoscopic observation of a scene. In the context of nonphotorealistic 3D imaging and reconstruction systems, the authors introduce general principles and also demonstrate camera calibration for 3D imaging, smart cameras, and full-link imaging methods using the optical modulation transfer function to improve imaging quality in conventional cameras. The second category is based on light-ray light field technology to achieve photorealistic 3D imaging and displays. In the context of light-ray light field systems, two approaches capable of light-ray light field 3D imaging by utilizing a camera array or a lens array are demonstrated. Accordingly, light-ray light field display approaches comprising head-mounted displays and integral displays are also introduced. The third category is also photorealistic 3D imaging and display technology, which is based on holography (i.e., diffraction or wavefront light field). In the corresponding holographic displays, the authors introduce 3D holographic displays from three elements: algorithms, devices, and systems, involving fast hologram generation algorithms, wide-viewing-angle display systems, and metasurface holography, etc. Including an investigative roadmap for future progress in optical imaging and 3D display systems, this book is essential reading for scientists and engineers in academia and industry who are interested in next-generation imaging and display concepts for 3D visual sensing systems.
