摘要

本篇論文描述了本實驗室在台俄任務(MAI)所開發的雙波長氣暉光剖面儀中所使用的光電倍增管，在實際執行太空任務前的校正程序。欲校準的光電倍增管共有兩種，分別是用來量測630nm與135.6nm波長的大氣輝光。本平台利用標準光源照射光電倍增管，並搭配使用校準用的光功率感測器作為參照的方式，來建立出光電倍增管的敏感度特性曲線。為了實現這個方法，本研究設計了特殊的暗箱機構，其中包含了光路、氣路以及光衰減器的設計。在機構上考量了重用性及便利性，故多數元件的設計為卡槽抽換的形式。為了讓短波長的真空紫外光源能夠適用，故本平台也作了相應的氣路設計。實驗操作上的自動化則透過VMIO人機介面來作實現。

This paper describes the calibration procedure of photomultiplier tube before the actual implementation of space missions. These photomultiplier tubes is mounted on the payload developed by our laboratory in the MAI mission. There are two photomultiplier tubes need to calibrate , which are used to measure the airglow under the wavelength of 630-nm and 135.6-nm.The platform uses a standard light source to irradiate the photomultiplier tube and the calibrated optical power sensor head to establish the sensitivity characteristic curve of the photomultiplier tube.To achieve this goal, we have designed a special dark box mechanism. There are some designs in the dark box including light path, optical attenuator, and air passage design.In order to increase the reusability of the platform, swappable card slot, VMIO human-computer interface, and ventilation system are also built into the device.
