Overview
ABSTRACT
Terahertz electromagnetic waves have aroused the curiosity and enthusiasm of scientists and industrialists as they allow for a chemical analysis of materials in surface and volume. Complementary to existing technologies, terahertz spectral imaging presents a considerable potential for applications in the fields of biology, safety and the environment, for instance. This article recalls the fundamentals, limitations and latest evolutions in this rapidly developing field.
