Design of Space Atmospheric Polarization Observation Instrument

Abstract

Abstract. Map the sky polarization mode is an important feature of remote sensing observation sky effect, describes the polarization signal distribution in the whole sky. The observer instrument design of polarization image acquisition all sky in this paper is used to analyze the distribution of polarized light in the sky, the sky a preliminary determination of polarization distribution around several polarization neutral zone has ring distribution. Firstly, according to the atmosphere the polarization characteristics of information analysis, to determine the basic requirements of remote sensing polarization array design; secondly, gives the design idea of instrument all the components of the system; finally, to obtain the atmospheric observation chart like data processing, access to high quality space atmospheric polarization diagram. Basically meet the request of space atmospheric polarization observations. Atmospheric Distribution and Neutral ZoneDue to different regions, different observation angles correspond to different sky polarization modes. Therefore, the establishment of the sky polarization mode chart, the determination of the regional atmospheric neutral zone, is a prerequisite for the elimination of atmospheric effects.This paper intends to build a 0.8 meter diameter polarization adaptive observation device for observing atmospheric polarization neutral zone based on polarization array based on the observation times mirror, obtain rich atmosphere, surface feature polarization information to study the atmospheric window effect, ground inversion, radiometric calibration standard; instrument calibration and verification of gas separation equipment based on exploration gas separation, a systematic method of atmospheric and surface inversion error and instrument error separation, and explore other remote instrument calibration may provide for the comparison method; two group adaptive comparison experiment, comparing with ground -atmosphere detection value and groundSky atmospheric detection value, explore the atmospheric effect correction data set or expression, in order to eliminate the atmospheric transmission effect leads to provide long-term test means error. Design and Analysis of Polarization Remote Sensing ArrayIn order to get within a period of time full sky polarization distribution, apply for Peking University of continuous observation experiment, the sky is fine, the experiment in every 1 hour of all sky shot a set of data. Figure 2 is real-time shooting photos and the degree of polarization, polarization azimuth distribution comparison chart. 298
