Abstract

The invention discloses a 2 pi space polarization observation instrument, which includes a benchmark structure based on celestial division of 2 pi space, an azimuth and pitch integrated turntable control system with multi-angle observations on the hemisphere space, and an optical phase polarization imaging sequence system with variable phases and multi radian angles. The whole system works through a computer-controlling electric control box, and the electric control box is connected with an installation base plane, a two-axis turntable, the optical phase polarization imaging sequence system with variable phases and multi radian angles, a data recorder, and a data acquisition terminal. The whole system can obtain a sky polarization distribution pattern at any time, which provides data support for finding an atmospheric neutral region, a whole sky polarization field characterization and sky polarization vector lines of bionic polarization navigation.

Description

technical field [0001] The invention relates to a set of 2π space all-sky polarization observation instruments, which can realize the multi-angle measurement of the upper hemisphere space and obtain the sky polarization distribution mode at any time. The sky polarization vector line provides data support. Background technique [0002] Polarization, light intensity, frequency, and phase are the four main attributes of electromagnetic waves, but polarization has not been paid enough attention to and fully utilized. In fact, nature is full of various natural polarizers, such as vegetation, buildings, clouds, fog, etc. At present, more and more researchers have noticed the importance of polarization characteristics, and polarization instruments have gradually developed rapidly. Like various remote sensing instruments, instrument errors are intertwined with atmospheric effects and complex surface elements, and the true value of observations is difficult to pass through conventio...
