Abstract

APARELHO E MÉTODO PARA DETERMINAR AS CARACTERÍSTICAS DE UM FLUIDO. Divulga um aparelho para determinar as características de um fluido. O aparelho inclui um arranjo de LED que produz luz visível, um sistema óptico e um microcontrolador. No aparelho, o arranjo de LED que produz uma luz visível emite luz e produz um feixe de luz para irradiar um objeto. Além disso, no aparelho, o sistema ideal inclui uma grade para receber luz irradiada do objeto através de um colimador e dispersar a luz em comprimentos de onda, uma lente de focagem e um sensor de imagem linear dispostos em um plano focal da lente de focagem para converter a luz pela grade e focalizado pela lente de focagem, em sinais elétricos. Por fim, no aparelho, o microcontrolador é conectado ao sensor e processa os sinais elétricos e se comunica para processamento.
