A biological parameter such as blood glucose is measured by directing laser pulses from a light guide (10) into a body part consisting of soft tissue, such as the tip of a finger (12) to produce a photoacoustic interaction. The resulting acoustic signal is detected by a transducer (14) and analysed to provide the desired parameter.
On mesure un paramètre biologique tel que le glucose sanguin en dirigeant des impulsions laser depuis un conduit de lumière (10) dans une partie du corps formée d'un tissu mou, tel que le bout d'un doigt (12), afin de produire une interaction photoacoustique. Le signal photoacoustique résultant est détecté par un transducteur (14) et analysé pour obtenir le paramètre désiré.
