摘要
Methods and systems for detecting radiation, particularly, terahertz (THz) radiation, are disclosed. The methods and systems disclosed include directing an optical beam in a volume of gas; ionizing at least a portion of the volume of gas with the optical beam to produce a plasma; and detecting a fluorescence produced from an interaction of a radiation wave with the plasma. The information contained in the characteristics of the detected fluorescence, for example, the amplitude and/or phase are used to characterize the radiation wave. Aspects of the invention may be used for homeland security, medicine, and astronomy, among other fields.
