  • System for measuring a biological parameter by means of photoacoustic interaction
    Patent number: 6833540
    Abstract: A system for measuring a biological parameter, such as blood glucose, the system comprising the steps of directing laser pulses from a light guide into a body part consisting of soft tissue, such as the tip of a finger to produce a photoacoustic interaction. The resulting acoustic signal is detected by a transducer and analyzed to provide the desired parameter.
    Type: Grant
