Abstract

A Swedish-built uv spectropolarimeter to be launched on a Soviet satellite in the Intercosmos series is described. The scientific objective is to record linear polarization across monochromatic solar images formed in resonance lines in the 130-150-nm wavelength region. This polarization arises by coherent scattering in the chromosphere-corona transition region of the sun. The instrument uses two parallel optical channels with highly different polarizing properties. The polarization analysis is done by reflection at gold-coated mirrors. The uv calibrations of the two flight models are described.

摘要

本文描述了一台将搭载在苏联“国际宇宙”系列卫星上的瑞典制造的紫外分光偏振计。其科学目标是记录在130 - 150纳米波长区域内由共振线形成的单色太阳图像上的线性偏振。这种偏振是由太阳色球 - 日冕过渡区的相干散射产生的。该仪器使用两个具有截然不同偏振特性的平行光学通道。偏振分析通过在镀金镜面上的反射来完成。文中还描述了两个飞行模型的紫外校准情况。
