【Abstract】 Pulsed terahertz (THz) radiation is a newly developed coherent far infrared source, which has been applied in many rescarch fields. In this paper, the mechanisms and methods of its generation and detection arc introduced. The properties and its uniqueness in applications to biological rescarches are discussed. A brief review is given to the latest progress in THz time-domain spectroscopy and imaging on biological samples, and the prospcct of the rescarch in this cross-cliscipline is presentcd.更多还原
