Espectroscopia Por Mapeamento RGB de Fontes Primárias de Luz

Authors: M. Simões F., R. Gobato

Spectroscopy is a technique for collecting physicochemical data through the transmission, absorption or reflection of incident radiant energy in a sample. It is much employed to be used in their spectra, which is difficult to access equipment because of its high cost, found in research surveys. Our work is used in common low cost and easy access devices that have a CCD reader, which is replaced by these spectrometers. We determine mathematical parameters that characterize by mapping the images obtained by common cameras such as: cell phones, smartphone, tablet, iphone, ipad, webcam, etc. As filming obtained by optical CCD reader theses hardware, form decoded and separated into their quantified RGB E color channels. Our technique consists of the analysis of the pixels of the images of primary light sources, such as: the sun, incandescent lamps, fire, candle flames, matchestick flame, wood combustion, etc.
