Title:
TERAHERTZ FULL-POLARIZATION-STATE DETECTION SPECTROGRAPH
Document Type and Number:
WIPO Patent Application WO/2018/058798
Kind Code:
A1
Abstract:
A terahertz full-polarization-state detection spectrograph, comprising a terahertz wave generator (10), a polarizer (11), a polarizing beam-splitting sheet (12), a horizontal terahertz detector (13), and a vertical terahertz detector (14). The terahertz wave generator (10) generates a terahertz wave and the purity of the terahertz wave is optimized by the polarizer (11); a measured object modulates the terahertz wave the purity of which is optimized to obtain a terahertz modulated wave; the polarizing beam-splitting sheet (12) decomposes the terahertz modulated wave into a horizontal terahertz wave and a vertical terahertz wave which are vertical to each other in a polarization state; the two corresponding terahertz detectors (13, 14) are used for measuring the two terahertz waves respectively, and then the characteristics of a measured sample (50) are analyzed according to the measurement result. The terahertz full-polarization-state detection spectrograph can quickly measure full-polarization-state terahertz waves accurately, thereby improving the measurement precision and measurement efficiency of the measured sample (50).
