Resumo(s)
O principal objetivo do trabalho realizado foi criar as bases necessárias, com a ajuda do software
de simulação ótica, Zemax OpticStudio, para simular a oximetria de pulso. Com o aumento
constante da utilização destes dispositivos, é cada vez mais necessário encontrar novos métodos
que ajudem a medir e a melhorar a sua precisão antes de chegarem à fase de protótipo e
construção.
Assim, pretendeu-se criar modelos no OpticStudio que pudessem ser facilmente alterados por
qualquer utilizador, de modo a poderem ser utilizados em qualquer fase do desenvolvimento do
oxímetro de pulso. Uma vez montados, o objetivo era procurar valores que caracterizassem a
forma como o sangue e a pele interagiriam com a luz, para que pudessem ser utilizados em
simulações para validar as montagens efetuadas.
Por fim, quis-se criar uma forma de automatizar as simulações com a ajuda de código para que
qualquer pessoa pudesse utilizar as montagens e fazer os estudos que quisesse com o mínimo de
esforço possível. Foi ainda analisada a possibilidade de criação de uma interfase gráfica que
servisse de ponte para o OpticStudio e permitisse ao utilizador não ter de interagir com o
programa, tendo-se observado que tal não era possível devido a limitações nas ferramentas de
código atuais.
The main objective of the work carried out was to create the necessary bases with the help of the optical design software Zemax OpticStudio to simulate pulse oximetry. With the constant increase in the use of these devices, there is an increasing need to find new methods to help measure and improve their accuracy before they reach the prototype and construction stage. The intention was therefore to create OpticStudio models that could be easily altered by any user, so that they could be used at any stage of the pulse oximeter's development. Once assembled, the aim was to search for values that would characterize how the blood and skin would interact to light, so that they could be used in simulations to validate the models created. Finally, we wanted to create a way of automating the simulations with the help of code so that anyone could take the models and do the studies they wanted with as little effort as possible. Efforts were also made to create a graphical user interface that would serve as a bridge to OpticStudio and there would be no need for the user to interact with the program, but this could not be implemented due to limitations in the current tools for coding.
