Abstract

The invention belongs to the technical field of terahertz wave detection, specifically discloses a terahertz wave detector, a detection system and a detection method. The terahertz wave detector comprises a lens for receiving a first optical signal and outputting a second optical signal after filtering and focusing, a detecting element for converting the second optical signal output by the lens to an electric signal to output, a signal amplifying circuit for filtering and amplifying the electric signal output by the detecting element to output, and a power supply for supplying work voltage to the detecting element and the signal amplifying circuit. The invention can detect terahertz wave to be beneficial to all terahertz wave scientific and technical research and development.

Description

technical field [0001] The invention belongs to the technical field of terahertz wave detection, and in particular relates to a terahertz wave detector, a detection system and a detection method. Background technique [0002] Terahertz (Terahertz, THz, 1THz=10 12 Hz) waves refer to electromagnetic waves with a frequency in the range of 0.1THz to 10THz (that is, a wavelength of 3mm to 30μm). THz waves have good penetrability to many dielectric materials and non-polar liquids, and can detect opaque objects through perspective; their photon energy is very low, which is safe for living organisms; THz waves contain rich spectral information and have Good spectral resolution characteristics. Therefore, THz technology has unique advantages in fields such as biomedicine and safety monitoring. [0003] Terahertz wave radiation source and terahertz wave detection technology affect the development of all other terahertz wave science and technology research. However, the prior art d...
