Abstract

For the past twenty years, TeraView has been a world leader in the application of terahertz pulses to solve problems for industry.Terahertz technology provides the opportunity of remote, safe, fast and accurate sensing. In recent years, there has been a growing interest from industry in applying terahertz pulses to process control.In this paper, there is a brief review of the generation and detection of terahertz waves (0.1 THz to 6THz) using photoconductive antennas.The applications of time-domain spectroscopy to gas, liquid and solids are discussed.Then, a number of industrial applications ofterahertz pulsed imaging such as solar cells, pharmaceutical, battery production and automotive industries are highlighted.
