PROBE, SYSTEM, AND METHOD FOR NON-INVASIVE MEASUREMENT OF BLOOD ANALYTES

摘要

The present disclosure concerns a measuring probe (10) for non-invasive in vivo measurement of blood analytes (33) by Raman spectroscopy. The measuring probe (10) comprises a housing (20) having a skin engaging surface (21). The housing (20) comprises a first optical system (1,3,4) arranged for providing source light (11) to the skin engaging surface (21) for penetrating a subject's skin (31) by said source light (11) for interacting with the blood analytes (33). The housing (20) further comprises a second optical system (5,6,2) arranged for capturing scattered Raman light (12) from the blood analytes (33) for measurement of the blood analytes (33). The first optical system (1,3,4) is arranged for providing the source light (11) as a collimated beam (1c) onto the skin (31).
