摘要：
A system for optical spectroscopy through a probe (10) implanted in a tissue, the system including a light collecting probe (10) comprising a waveguide formed by a single optical fiber (11) and having a proximal end (11a) and a distal end (11b), the proximal end (11a) being formed with a taper (12) along which at least one optical window (11c) is positioned, wherein light entering at an axial section of the taper (12) generates a specific subset of guided modes defined by the diameter (a1, a2, . . . , an) of the optical fiber at that axial section, the guided modes propagating toward the distal end (11b) of the waveguide and generating an output (OUT) at the distal end of the waveguide； a demultiplexer (20) configured to receive outputs (OUT) provided by the probe (10) and discriminate the outputs (OUT) based on their modal content of origin； and a detector (30) configured to detect the discriminated outputs.
