Study on full-polarization hyperspectral imaging technology

Since full-polarization parameter measurement can not be well combined with hyperspectral imaging technology yet,a new full-polarization hyperspectral imaging measurement structure using a dual optical path system is investigated.Using the hyperspectral interference imaging technology and polarization modulation technology based on electro-optic effect,the polarization information,spectral information and spatial image information are effectively combined,the synchronous measurement of hyperspectral information and full-polarization parameter is realized.The principle of the full-polarization parameter measurement is introduced at first.Then the experiment setup is shown and the optical elements are illustrated.Also,the detailed formula derivation steps of the full-Stokes vector is given.At last,some computer simulation data and experimental results are given.Through the combination of spectral imaging and full-polarization parameter measurement,the detecting information of the object is greatly enriched.The feasibility of this method is verified through simulation results.This work will definitely be helpful to many optical remote sensing technology areas such as resources survey,environmental monitoring and military reconnaissance.
