APPLICATION
Fuel combustion is a transient chemical reaction kinetic process. Scientists use traditional photoelectric technology, combined with laser technology, spectroscopy technology, and image processing technology to analyse the temperature, composition and other parameters of the combustion field, and optimize the spray combustion of the engine. It is of great significance to improve combustion efficiency and reduce pollutants.
Endoscopy technology has been widely used in the field of pre-medical diagnosis. With the development of endoscopy technology, the interaction between light and biological tissues has play a role in early diagnosis and disease prevention. Various optical methods (such as reflection, absorption, fluorescence, scattering, etc.) have been used.
In this paper, the hyperspectral data of the test object were collected by using the hyperspectral imager Gaia-Field (spectral range 400 nm -1000 nm) of Jiangsu Shuangli Hepu Technology Co. Ltd.
等离子体一直是物理研究中非常重要的一个方向,涉及的研究方向包括:等温等离子体,燃烧,爆炸,LIBS,激光加工等等,并在工业领域具有广泛的应用场景。在涉及等离子体的一系列研究方向中,有一种普遍的需求,了解等离子体由何种成分构成,以及其如何随时间变化,及测试等离子体的关键参数:温度和自由电子、离子浓度。 为了收集此类信息,我们需要同时进行等离子成像和等离子体光谱测试。
时间分辨光谱广泛用于材料/相互作用的动态特性以及动力学过程分析,其应用涵盖激光与放电等离子体,燃烧与爆炸,光伏,光催化,原子分子动力学,化学反应动力学,生物医学,半导体材料载流子动力学等方向。传统的时间分辨光谱方法,或需要多次重复实验(如使用PMT类高速单点探测器或ICCD类快速门控探测器),或需要较高的成本(如分幅相机、条纹相机、高速线阵/面阵探测器等),且灵敏度、分辨率、动态范围比普通科研级光谱相机相距甚远。
