摘要: 空間原子氧環(huán)境是低地球軌道空間環(huán)境的重要組成之一,，未來的原子氧探測技術要求探測載荷不僅在重量和功耗方面比現(xiàn)有技術大幅降低，而且在探測性能上要有極大的提升,，特別是能實現(xiàn)原子氧通量的實時探測,。文章在分析目前主要原子氧探測類型及其特點的基礎上,，提出一種基于碳納米管氣體傳感器的原子氧探測技術。其探測儀器具有體積小,、功耗低,、靈敏度高、可實時探測,、能長期連續(xù)工作,、可重復使用等特點，是納米傳感器技術發(fā)展的重要方向,。該技術一旦成功應用,，有望快速提高我國在原子氧探測方面的技術水平。Abstract: The space atomic oxygen is an important issue in the space environment. The future AO detection technique requires a light weight and a reduced power consumption of the related AO sensors, to allow for the in-situ measurement of the space AO fluence. Based on the analysis of major AO detection methods and their characteristics, a technique using the carbon nanotube gas sensor is proposed for the low-content atmosphere detection. The sensor features the small size, the low power consumption, the high sensitivity and the quick response, which can work continuously and repeatedly, represents an important direction for nano sensors, and could be used for the AO fluence measurement to improve the technical level of China's AO detection.
