英文摘要: Hyperspectral imaging (HSI) can provide valuable information about the spatial distribution ofingredients in an object, therefore the technique has been widely adopted in numerous applications, rangingfrom remote sensing and land planning, food quality control, to biomedical applications. However, HSIinstruments are expensive, which has limited the technique to some high-end applications. In this study, wedeveloped a cost-effective HSI technique with an internal scene-scan mechanism, which enables rapidacquisitions of a scene without moving the instrument or the tested object. The apparatus was characterised,revealing an imaging resolution of 0.4 mm in a field of view (FoV) of 10 cm and a spectralresolution of 1.3 nm in the 40–800 nm visible light region. We succeeded in applying...
