Claim Text:
1. A system for detecting a number of layers of a few-layer graphene (FLG), the system comprising: a visualization module comprising a structure for holding and illuminating an FLG sample; an acquisition module comprising a structure for performing an optical observation on the FLG sample; and a reproduction module comprising a structure operably connected to the acquisition module for providing information of detection of the number of layers of the FLG; wherein the visualization module comprises a platform member and an illumination member; the illumination member comprises a structure selected from a group consisting of: a) a reflective structure projecting a light reflectively to the platform member; b) a beaming structure directly providing a light through the platform member; and c) a structure comprising both the reflective structure and the beaming structure and capable of switching between the reflective and beaming structures; wherein the visualization module further comprises a magnification member comprising a structure for magnifying an image of the FLG sample held by the platform member; wherein the acquisition module comprises: the reproduction module a) receives the information of the focused magnified image of the FLG sample from the capturing member, b) spectrally analyzes the information of the focused magnified image, c) categorizes the information of the focused magnified image in terms of determining the number of layers of the FLG according to a database built by multispectral analyses and principal component analyses (hereinafter “PCA”) for providing a relationship between a number of layers of an FLG and a distinguishing formula in order to present a categorization result, d) performs chromatic enhancement according to the categorization result, e) performs color image reproduction and f) provides a reproduced color image.
