Abstract
The invention relates to a device for non-invasive monitoring of at least one compound in blood, comprising a radiation source configured to emit infrared radiation towards a body part, a Fabry-Pérot interferometer configured to modulate the infrared radiation, a thermal detector and a microphone configured to detect reflected infrared irradiation or photoacoustic emission. The device further comprises a processing unit to time-modulate the infrared emission and configured to determine an amount of the compound in blood based on the detected infrared irradiation and/or on photoacoustic emission; and/or a transmitter configured to transmit information on the detected infrared irradiation and/or photoacoustic emission to an external device for processing.
