Abstract

This paper presents a new kind of colour sensor based in measurement the three channels of RGB colour space, using bifurcated optical fibres to conduct light from illuminant to liquid under test and from liquid to photo sensor. This kind of colorimeter can be applied to wine industry in despite of using different colour space in relation to traditional methods.<br />This paper shows a brief description of colour measurement process, a prototype implementation and several experimental results to compare their results to colour data from commercial equipment, and to verify its applicability to wine industry.
