Abstract

a invenção refere-se a um aparelho de fotopletismografia (100), que compreende uma fonte de luz (110) configurada para fornecer luz de fonte (130) de pelo menos uma primeira e uma segunda posições direcionada a um tecido (140); um detector de luz (120) configurado para detectar luz de fonte e para fornecer pelo menos um primeiro e um segundo sinais de sensor (127, 29) indicativos da luz de fonte dispersa da primeira e da segunda posições espectrais; e uma unidade de processamento (150). a unidade de processamento é configurada para calcular um sinal de sensor corrigido (160), indicativo de uma variação na absorbância do sangue no interior do tecido, pela remoção de um componente de sinal de erro de trajetória no tecido, indicativo de uma variação no comprimento da trajetória óptica através do tecido ao longo do tempo, e um componente de sinal de erro do acoplamento de luz, indicativo de uma variação da intensidade de luz da fonte da luz da fonte emitida no tecido, do pelo menos primeiro e segundo sinais de sensor.
