PROBE HEAD FOR SPECTROSCOPIC ANALYSIS OF A FLUID

摘要

The present invention provides a spectroscopic system for determining a property of a fluid flowing through a volume of interest underneath the surface of the skin of a patient. The spectroscopic system comprises a probe head that has at least an objective for directing an excitation beam into the volume of interest and for collecting return radiation. The spectroscopic system has further a base station having at least a spectroscopic analysis unit and a power supply. The system makes use of a beam combination unit, a filter unit and a focusing unit for combining and separating a variety of different optical signals and for precisely positioning the optical signals inside the volume of interest. The beam combination unit, the filter unit and the focusing unit can be variably implemented inside the probe head or inside the base station depending on a specific applications of the spectroscopic system, thereby allowing for a flexible and compact design of the probe head.
