This book describes the current, concrete status of terahertz
(THz) technology applied to scientific diagnoses of cultural
heritage objects for conservation planning as well as for
historical interest. It is unlike other THz-related scientific
books in optics series, which only describe technologies and the
physics behind them. A new method utilizing THz technology is
introduced, which will help conservators and historians to
analyse art objects at their museums. By using pulse echoes, THz
imaging can noninvasively show internal structures such as layers
in paintings and internal defects or additional pieces in
objects. The biggest advantage of THz technology in heritage
science is that THz waves can reveal the condition of preparation
layers and supports of paintings that cannot be observed by other
nondestructive testing methods, such as infrared (IR) or X-ray
radiography. The condition of supports and preparation layers
determine the lifetime of the paintings, so that their condition
is the key factor for conservation planning.

The comparison with existing classic methods for scientific
analyses is extremely important in the context of introducing new
technologies in any research field, since most conservators and
heritage scientists have their own protocols for classic methods.
This book compares THz results not only with visible cross
sections obtained using destructive methods, but also mid-IR,
near IR, UV, X-ray, and nuclear magnetic resonance(NMR), which
are considered to be nondestructive methods.

The book suggests future work that can be done by THz
specialists, especially concerning the development of THz
cameras, and by engineers and scientists in other fields, such as
signal processing and chemistry, as well as by conservators.
