Title: OPTICAL SENSOR SYSTEM
Abstract:
An optical sensor system (21) is provided with: an optical sensor head (1), which has a light emitting device (2), and a detector (3) that detects light emitted from the light emitting device (2); and a calculation unit (51). The light emitting device (2) has a resonator that includes a first reflecting surface (4), a second reflecting surface (5) facing the first reflecting surface (4), and a waveguide (6) that is provided between the first reflecting surface (4) and the second reflecting surface (5). On the first reflecting surface (4), one or more metal fine particles capable of exciting surface plasmon are formed. On the basis of a detection value obtained from the detector (3), the calculation unit (51) calculates environmental parameters with respect to the first reflecting surface (4).
