高时间分辨的变象管分幅/扫描摄影技术与高光谱分辨的光棚光谱技术相结合,提供了光谱随时间变化过程的精密测量。它对于揭示快速变化的原子分子的微观动力学过程及鉴别中间产物有着重要的作用。 为了减少能量损失,尽可能缩小仪器体积,光谱头采用了平面反射闪耀光栅作为色散元件,以球面反射镜作为聚焦系统。
The combination of high time-resolved voxel framing / scanning photography with hyperspectral resolution light shedding spectroscopy provides a sophisticated measurement of the spectrum over time. It plays an important role in revealing the micro-dynamics of rapidly changing atomic molecules and in identifying intermediates. In order to reduce the energy loss, the volume of the instrument should be reduced as much as possible. The spectral head adopts a flat reflection blazed grating as the dispersion element and the spherical mirror as the focusing system.
