Development of skin characterisation techniques
using terahertz (THz) reflection spectroscopy

Physics

The use of terahertz (1THz = 1012Hz) waves, broadly defined as EM waves in the 0.1-10THz frequency range [1], in medical diagnosis is a rapidly developing area due to the strong a
enua
on of THz waves by biological materials of high water content [2]. This sensi
vity allows THz radia
on to be used as a non-ionizing and non-
invasive method in the diagnosis of skin condi
ons. However, the hydra
on of the skin’s surface layers is dependent on a large number of everyday factors that need to be understood such that dominant factors can be controlled.
