Terahertz photonics for imaging
15th International Conference on Microwaves, Radar and Wireless Communications (IEEE Cat. No.04EX824), 2004This paper concerns the application of microwave photonic techniques for Terahertz imaging. The system under investigation comprises of two high power, low noise electro-optic microchip lasers that mix in a traveling wave detector to produce a 200 GHz millimeter wave signal that is multiplied to .8 or 1.2 THz.

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

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.

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.

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).

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.
