Non-destructive inspection on the coatings of interior decoration with multispectral imaging module

The coatings used in indoor building materials is closely related to the health of the residents and the global environment. In order to quickly and easily identify the composition of coating samples on indoor building materials, this study utilizes a multispectral imaging module with different light sources from wavelength 400 nm to 1000 nm to detect transmittance, reflectance, and characteristic fluorescence in different wavelength bands.
