Abstract

Abstract. The Sunrise Chromospheric Infrared spectroPolarimeter (SCIP) has been developed for the third flight of the Sunrise balloon-borne stratospheric solar observatory. The aim of the SCIP is to reveal the evolution of three-dimensional magnetic fields in the solar photosphere and chromosphere using spectropolarimetric measurements with a polarimetric precision of 0.03% (1σ). Multiple lines in the 770 and 850 nm wavelength bands are simultaneously observed with two 2 k × 2 k CMOS cameras at a frame rate of 31.25 Hz. Stokes profiles are calculated onboard by accumulating the images modulated by a polarization modulation unit, and then compression processes are applied to the two-dimensional maps of the Stokes profiles. This onboard data processing effectively reduces the data rate. SCIP electronics can handle large data formats at high speed. Before the implementation into the flight SCIP electronics, a performance verification of the onboard data processing was performed with synthetic SCIP data that were produced with a numerical simulation modeling the solar atmospheres. Finally, we verified that the high-speed onboard data processing was realized on ground with the flight hardware using images illuminated by natural sunlight or an LED light.

用于sunrise III气球望远镜的日出色球红外分光偏振计的高速数据处理

摘要为“日出”平流层太阳观测站的第三次飞行研制了“日出”色球红外分光偏振仪。SCIP的目的是利用偏振光谱测量揭示太阳光球和色球中三维磁场的演变，偏振精度为0.03% (1σ)。利用两台2k × 2k CMOS相机，以31.25 Hz的帧率同时观测到770和850 nm波长波段的多条线。通过对偏振调制单元调制后的图像进行累加，计算出Stokes剖面，然后对Stokes剖面的二维图进行压缩处理。这种机载数据处理有效地降低了数据速率。SCIP电子设备可以高速处理大数据格式。在将SCIP应用于飞行电子设备之前，对机载数据处理进行了性能验证，并使用太阳大气数值模拟生成的合成SCIP数据进行了验证。最后，我们验证了高速机载数据处理是在地面上与飞行硬件使用自然阳光或LED灯照明的图像实现的。
