Projeto e desenvolvimento de um sistema dedicado ao controle e aquisição de dados para um detector de alta resolução espectral.

Abstract

This work presents a proposal for the design and construction of a data acquisition system for a multispectral optical detector, based on Variable Interference Filters (VIF) that incorporates a resonant Fabry-Perot layer, inclined within the optically active area of the VIF, which can function as a low-cost spectrophotometer for teaching purposes. The development of this device composed of the multispectral detector and the dedicated software system involved the study of microelectronics of its components, to guarantee the prediction of the configuration between these components in its assembly. Also part of the study is the analysis of requirements and programming in different development environments so that the system is adaptable to the software in question. To ensure the portability of the developed system, research was carried out so that the development and technology environments used are adaptable and malleable. As for the detector, to ensure that the system adapts to teaching purposes, its components in the assembly present a certain mobility, so that they can later be calibrated. This mobility is obtained in the supports of these components. Finally, for the device to generate data that can be transmitted remotely, an architecture based on the Internet of Things (IoT) was created and developed. The development of research involving multidisciplinary studies and their stages can contribute to an environment of scientific dissemination, with emphasis on electromagnetic waves, microelectronics manufacturing processes, spectrophotometry, microcontroller programming and software development, which are developed for the device presented at the end.
