Abstract

A simple near infrared grating spectrometer is described which employs a dry ice-cooled photomultiplier tube used in the pulse counting mode. Spectral data is recorded on punched paper tape enabling a large number of low intensity spectra to be averaged. The instrument is particularly useful for the study of weak near infrared airglow and auroral emissions from the upper atmosphere.

摘要

本文描述了一种简单的近红外光栅光谱仪，它采用了在脉冲计数模式下使用的干冰冷却光电倍增管。光谱数据记录在穿孔纸带上，从而能够对大量低强度光谱进行平均。该仪器对于研究高层大气中微弱的近红外气辉和极光发射特别有用。
