Design and construction of real-time all-polarization imaging detector for skylight
摘要
Abstract
Researchers have been highly inspired by the bio-use of polarized light navigation,and in-creasing number of studies are being conducted at the same time.A precise sky polarization field map is one of the prerequisites for polarization navigation and many imaging polarization detectors have thus been developed for attaining a more accurate sky polarization field map.This study proposes a novel real-time all-polarization imaging detector that can obtain all the parameters of the Stokes vec-tor,and can thereby calculate various attributes of Angle of Polarization(AOP),Degree of Polariza-tion(DOP),Degree of Linear Polarization(LDOP),and Degree of Circular Polarization(CDOP).By incorporating the M FC architecture through C+ + programming language and the OpenCV library, the host computer program was developed for implementing the real-time display function of a target's polarization information.Refresh rate of the video stream was 3 frame/s at maximum resolution, w hich primarily satisfies the need of real-time detection.Observation of the sky polarization field map was performed under clear weather conditions and the performance of the detector was found to be sta-ble during the course of the proposed experiment.T he obtained experimental results are in good a-greement with the Rayleigh scattering model,and the dynamic recognition deviation of the solar me-ridian can range from 0.01°to 0.23°,which corroborates the reliability of the proposed detector and lays the foundation for future work.关键词
