Here we describe the implementation and calibration of a streaked visible spectrometer (SVS) for optical pyrometry and emission/absorption spectroscopy on light gas gun platforms in the UC Davis Shock Compression Laboratory. The diagnostic consists of an optical streak camera coupled to a spectrometer to provide temporally and spectrally-resolved records of visible emission from dynamically-compressed materials. Fiber optic coupling to the sample enables a small diagnostic footprint on the target face and flexibility of operation on multiple launch systems without the need for open optics. We present the details of calibration (time, wavelength and spectral radiance) for absolute temperature determination and present benchmark measurements of system performance.

在美因茨的Kaos光谱仪中，运行着一个高分辨率的高能粒子坐标探测器。它由直径为4000个< 1mm and is read out by >多阳极光电倍增管通道的增强纤维组成。它是世界上最先进的磁谱仪焦平面探测器之一。为了校正由不同的增益和不同的光学透射率引起的检测效率的变化，已经开发了全自动离线校准程序。该过程包括将放射性同位素源定位在探测器平面旁边以及自动采集和分析探测器信号。可以通过低程度的人工交互来校准和校准每个单独的光纤通道。

The Airborne Infrared Spectrometer: Development, Characterization, and the 21 August 2017 Eclipse Observation
2017年8月21日，机载红外光谱仪（AIR-Spec）在距离NSF/NCAR湾流V研究飞机14公里的高度观测到日全食。该仪器成功地观测到了它被设计用来测量的五条日冕发射谱线：Si X 1.431 $μ$ m、S XI 1.921 $μ$ m、Fe IX 2.853 $μ$ m、Mg VIII 3.028 $μ$ m和Si IX 3.935 $μ$ m。确定这些磁敏感发射线的特征是设计未来仪器监测日冕磁场的重要第一步，日冕磁场驱动空间天气事件以及日冕加热、结构和动力学。AIR-Spec仪器包括图像稳定系统、馈源望远镜、光栅光谱仪和狭缝式成像仪。本文详细介绍了仪器的设计、光学准直方法、图像处理和数据标定方法。介绍了日食观测情况，并对现有资料进行了总结。
