Food product safety is a public health concern. Most of the food safety analytical and
detection methods are expensive, labor intensive, and time consuming. A safe, rapid …

We discuss the progress in the field of THz imaging based on time-domain spectroscopy
during the last 20 years emphasizing several highlights. These include 3D mapping of the …

Within the field of terahertz science and technology, one of the most active areas of current
research focuses on the intersection of terahertz measurements and methods with the world …

The birth of terahertz imaging approximately coincides with the birth of the journal Optics
Express. The 20^ th anniversary of the journal is therefore an opportune moment to consider …

Science and technologies based on terahertz frequency electromagnetic radiation (100 GHz–
30 THz) have developed rapidly over the last 30 years. For most of the 20th Century …

The field of terahertz science and technology has been an active and thriving research area
for several decades. However, the field has recently experienced an inflection point, as …

In this paper, we will review both past and recent progresses in the generation, detection
and application of intense terahertz (THz) radiation. We will restrict the review to laser based …

Over the past three decades a new spectroscopic technique with unique possibilities has
emerged. Based on coherent and time‐resolved detection of the electric field of ultrashort …

Terahertz (THz) waves are non-ionizing radiations with unique properties of both microwave
and infrared. THz imaging and spectroscopy have been widely used for non-destructive …

Principles of Terahertz Science and Technology aims to elucidate the fundamentals of THz
technology and science for potential new users. It surveys major techniques of generating …
