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.
等離子體一直是物理研究中非常重要的一個方向,涉及的研究方向包括:等溫等離子體,燃燒,爆炸,LIBS,激光加工等等,并在工業(yè)領域具有廣泛的應用場景。在涉及等離子體的一系列研究方向中,有一種普遍的需求,了解等離子體由何種成分構成,以及其如何隨時間變化,及測試等離子體的關鍵參數(shù):溫度和自由電子、離子濃度。 為了收集此類信息,我們需要同時進行等離子成像和等離子體光譜測試。
時間分辨光譜廣泛用于材料/相互作用的動態(tài)特性以及動力學過程分析,其應用涵蓋激光與放電等離子體,燃燒與爆炸,光伏,光催化,原子分子動力學,化學反應動力學,生物醫(yī)學,半導體材料載流子動力學等方向。傳統(tǒng)的時間分辨光譜方法,或需要多次重復實驗(如使用PMT類高速單點探測器或ICCD類快速門控探測器),或需要較高的成本(如分幅相機、條紋相機、高速線陣/面陣探測器等),且靈敏度、分辨率、動態(tài)范圍比普通科研級光譜相機相距甚遠。
