wave spectrometer

It can gives color difference of objects based on semispherical spectral reflectance in visible and near infrared wave bands measured by its internal spectrometer.

它利用其内置的光谱仪可测得可见-近红外波段反射物体的半球空间的反射比，继而可反演出物体的色度特性。

The measurements of the radio spikes with high time and frequency resolution by the spectrometer in Beijing Observatory may provide a self consistent diagnosis for the ambient plasma parameters ( magnetic field, density, temperature, wave vector, and the properties of nonthermal electrons).

利用北京天文台高时间和高频率分辨率的射电频谱仪对射电尖峰的测量，可以对背景等离子体参数进行的自洽诊断（磁场，密度，温度，波矢，及非热电子的性质）。
