We demonstrated some imaging applications of THz radiations, such as non-destructive detection of illicit drugs in a envelope. We also demonstrated a high sensitive terahertz sensing application by using a resonant transmission phenomenon of metal hole array which is attributed to a excitation of surface waves.

ABSTRACT The application of THz plasmonics in imaging dielectric objects embedded in the metallic media is presented. Signatures of the embedded object was detected when the time domain information of the transmitted pulse was analyzed by THz time domain spectroscop y. The resolution of the acquired images was enhanced by using a super-resolution image

We report on a configuration of confocal spatial filtering applied to terahertz imaging. Theoretical analysis of the confocal terahertz imaging layout agrees fairly well with the experimental observations of the enhancement of optical resolving power, both lateral and axial, leading to three-dimensional optical slicing, in comparison with the image ...

There is significant interest in the study of terahertz spectroscopy and imaging particularly dealing with the interaction of terahertz radiation with biological molecules, cells, and tissues (Smye et al. Physics in Medicine and Biology, 46(9):R101–R112, 2001).

Imaging at Terahertz Frequencies
Optical Solutions for Homeland and National Security, 2005Despite a century of research, the terahertz (1012 Hz) still remains the most immature and underutilized part of the electromagnetic spectrum. This talk will discuss the emerging application of THz imaging and will describe ongoing technology developments which will enable the practical realization of THz imaging.

The slice of the electromagnetic spectrum sandwiched between the infrared and microwave regions used to be known as the “terahertz gap” because scientists lacked the tools to access it. Not anymore. “In the last several years, terahertz spectroscopy has really found its footing,” says Yale University’s Charles A.

Advances in THz technology have propelled terahertz (THz) radiation to be an important part of the electromagnetic spectroscopic region. The THz frequency range excites large amplitude vibrational modes of molecules and allows researchers to probe weak interactions (Wallace et al. Faraday Discussions 126:255–263, 2004a; Faraday Discussions, 126:255–263,

The past 30 years have witnessed the evolution of medical imaging. Imaging technology has drastically improved medical care and, as a result, everyday life. Since the discovery of X-rays by William Roentgen in 1895, doctors have used radiography to diagnose many diseases of the internal organs for several decades.
