Research On Room Temperature Terahertz Focal Plane Detector Testing And Imaging System

The terahertz(THz) wave is a type of electromagnetic wave with the frequency of 0.1~10 THz and the wavelength of 30µm~3mm. Compared with other electromagnetic waves, THz wave has many unique properties, such as high penetration, wide broadband, lower energy and spectral identification capability. THz detection technology has been widely used, not only in the field of military communication and aerospace vehicle nondestructive testing, but also in civilian are such as security inspection, biomedical science, explosive detection, spectrum analysis, etc. THz technology has been paid more and more attention to currently in the world as a promising technology. With the rapid development of THz technology, there is higher requirement for the THz detection and the detector's performance. In order to meet this requirement, it is essential to carry out the research on the room temperature THz detector and its test verification imaging.
