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(gè)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(lǐng)域具有廣泛的應(yīng)用場(chǎng)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(gòu)成,以及其如何隨時(shí)間變化,及測(cè)試等離子體的關(guān)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(shí)進(jìn)行等離子成像和等離子體光譜測(cè)試。
時(shí)間分辨光譜廣泛用于材料/相互作用的動(dòng)態(tài)特性以及動(dòng)力學(xué)過(guò)程分析,其應(yīng)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(dòng)力學(xué),化學(xué)反應(yīng)動(dòng)力學(xué),生物醫(yī)學(xué),半導(dǎo)體材料載流子動(dòng)力學(xué)等方向。傳統(tǒng)的時(shí)間分辨光譜方法,或需要多次重復(fù)實(shí)驗(yàn)(如使用PMT類高速單點(diǎn)探測(cè)器或ICCD類快速門控探測(cè)器),或需要較高的成本(如分幅相機(jī)、條紋相機(jī)、高速線陣/面陣探測(cè)器等),且靈敏度、分辨率、動(dòng)態(tài)范圍比普通科研級(jí)光譜相機(jī)相距甚遠(yuǎn)。
