Abstract

Official abstract text for this publication.

A material may be identified using THz radiation that simultaneously or sequentially includes at least one first frequency portion and a second frequency portion different therefrom. An object formed from the material to be identified is irradiated with the THz radiation and the THz radiation exiting the object is detected using a phase-sensitive THz receiver. A time or phase offset, caused by the object, is measured at least for the first frequency portion and a material thickness is determined therefrom. Attenuation of the received signal, at least for the second frequency portion, is determined. An absorption coefficient for at least the second frequency portion is calculated using the material thickness.

First claim

Opening claim text (preview).

The invention claimed is: 1. A method of identifying a material from a class of materials that are transparent to THz radiation, the method comprising: producing THz radiation via a THz emitter, the THz radiation simultaneously or sequentially containing at least one first frequency component and a second frequency component of a wavelength which is different from the first frequency component, wherein absorption of the first frequency component of the THz radiation is lower than…
