Other Applications

Solar cells / Photovoltaics

Researchers at East China Normal University in Shanghai have developed a hyperspectral imaging system that is used to identify cracks and characterize other contaminants and defects early in the production cycle of solar cells. Hyperspectral images capture the diffuse light reflectance to distinguish cracks on polished specular surfaces (Li, 2010). Film thickness measurement during production is another important HSI application.
