NOVELTY - The present invention relates to a system employing image analysis for detecting the number of graphene layers and having an acquisition image module, an image enlarged module and a multispectral color image reproduction module. An aspect of the present invention relates to a method having a procedure for constructing a database to store information of graphene layers spectra and a procedure for detecting grapheme layers with multi-spectral color reproduction image, whereby the former has steps of analyzing grapheme layers spectra, performing principal component analysis (PCA), classifying grapheme layers, and building a database, and the latter has steps of retrieving an image, analyzing graphene spectra, categorizing grapheme layers, performing color enhancement, reproducing a color image and detecting the number of grapheme layers. The system and method in accordance with the present invention, using simple device, facilitate and simplify the detection of the number of graphene layers.
