Abstract
Disclosed is a fluid monitoring apparatus. The fluid monitoring apparatus includes a chamber configured to store a fluid, a resonator in the chamber, a light source disposed on the chamber and configured to provide pump light to the resonator, a detector configured to detect laser light generated in the resonator, and a control unit connected to the detector and the light source and configured to identify a physical quantity in the fluid by detecting a resonance wavelength of the laser light using a detection signal of the laser light.
