Material parameter estimation with terahertz time-domain spectroscopy.

Journal of the Optical Society of America A, 2001
Imaging systems based on terahertz (THz) time-domain spectroscopy offer a range of unique modalities owing to the broad bandwidth, subpicosecond duration, and phase-sensitive detection of the THz pulses.

Terahertz Time-Domain Spectroscopy

2021
This chapter aims to serve as an overview of the basic technology and experimental techniques that the work presented in later chapters of this thesis expands on and develops. Section 2.1 will introduce and provide background to the main methods of generating broadband pulses of THz radiation used throughout this thesis, while Sect.

Anisotropic complex refractive index of β-Ga2O3 bulk and epilayer evaluated by terahertz time-domain spectroscopy

, 2021
Homoepitaxial film and semi-insulating bulk β-Ga2O3 with (001) orientation were studied using terahertz time-domain spectroscopy (THz-TDS) in the frequency region from 0.2 to 3.0 THz parallel to the [100] and [010] directions.

Terahertz Time-Domain Spectroscopy in Reflection Configuration for Inorganic and Mineral Pigment Identification

Applied Spectroscopy, 2022
This work demonstrates terahertz time-domain spectroscopy (THz-TDS) in reflection configuration on a class of inorganic and mineral pigments. The technique is validated for pictorial materials against the limitations imposed by the back-reflection of the

Terahertz time-domain spectroscopy of water vapor.

Optics Letters, 1989
We describe the application of a new high-brightness, terahertz-beam system to time-domain spectroscopy. By analyzing the propagation of terahertz electromagnetic pulses through water vapor, we have made what we believe are the most accurate measurements to date of the absorption cross sections of the water molecule for the nine strongest lines in the ...

Key Differences of the Hydrate Shell Structures of ATP and Mg·ATP Revealed by Terahertz Time-Domain Spectroscopy and Dynamic Light Scattering.

Journal of Physical Chemistry B, 2021
ATP is one of the main biological molecules. Many of its biological and physicochemical properties, such as energy capacity of the phosphate bonds, significantly depend on hydration.

Terahertz quasi-time-domain spectroscopy imaging

Applied Optics, 2011
We demonstrate terahertz (THz) imaging with a quasi-time-domain spectrometer. This type of THz system is inexpensive, compact, and relatively easy to set up. Beating the simultaneously emitted equidistant modes of a compact diode laser allows for analysis of samples at multiple frequencies with a single measurement.

Polarimetric terahertz time-domain spectroscopy

SPIE Proceedings, 2012
One polarization measurement technology is proposed to apply in the basic Terahertz time domain spectroscopy (THz- TDS) using only one rotatable polarizer. The method to upgrade such a polarimetric Terahertz time-domain Spectroscopy (P-THz-TDS) was presented.
