论文摘要
在这里，我们描述了在UC Davis Shock压缩实验室中的轻型燃气枪平台上，用于光学上的光谱法和发射/吸收光谱的条纹可见光谱仪（SVS）的实现和校准。诊断包括一个耦合到光谱仪的光学条纹摄像头，以提供动态压缩材料可见发射的时间和光谱记录。光纤耦合到样品，可以在目标面上进行较小的诊断足迹，并在多个启动系统上的操作灵活性，而无需开放光学。我们介绍了用于确定绝对温度的校准（时间，波长和光谱辐射）的细节，并目前对系统性能进行基准测量。
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.
