TLDR
In this article, the authors provide details of recent developments in terahertz (THz) imaging technology and its applications, and discuss the properties, perceived imaging uses and sources of THz radiation.Abstract:
Purpose – The purpose of this paper is to provide details of recent developments in terahertz (THz) imaging technology and its applications.Design/methodology/approach – This paper first discusses the properties, perceived imaging uses and sources of THz radiation. It then describes passive and active imaging systems through reference to commercial products and their applications. Finally, it considers future prospects and key technological developments.Findings – This paper shows that the commercialisation of passive and active imaging systems has been gradual but uses are emerging in a range of security, material testing and healthcare applications. Market development has been hindered in part by the high cost of systems and certain technological and operational limitations. Research which aims to overcome these problems is widespread and much involves the development of improved sources and detectors.Originality/value – The paper provides a detailed insight into the present state of THz imaging technol...read more

Quantitative investigation of the bioeffects associated with terahertz radiation
Gerald J. Wilmink,Gerald J. Wilmink,Benjamin D. Rivest,Bennett L. Ibey,Caleb L. Roth,Joshua A. Bernhard,William P. Roach +6 more
TL;DR: Although the THz-exposed cells exhibited increases in heat shock protein expression, the magnitude of these increases was comparable to those observed in hyperthermic controls, suggesting that the biological effects imposed by THz radiation appear to be primarily photothermal in nature.
