Diseño y Construcción de un Prototipo de Espectrómetro no destructivo, en la luz visible

Abstract

In the present project the design and construction of a spectrometer in the visible light was realized. This equipment analyzes the spectral trace of each object through the reads of the electromagnetic waves. This is based on the analysis of absorption and reflection spectroscopy. As the study case this project determine the ripening of the banana from its tender state of decomposition. The parameters to be analyzed are: color through a color sensor and the level of light reflected in the banana through a light intensity sensor. This analysis is done after the sample is irradiated with some energy source in the range of visible light. The color measurement system to be used is the RGB (Red Green Blue).This system measures the intensity of each RGB color component emitted by the analyzed object through the color sensor that uses different color filters. An ARDUINO MEGA’s programming card is use to obtain the data in the Matlab’s program in order to analyze them.
