Patent ID: 8617470

Claim:
A system comprising: a light source configured to emit broadband Gaussian light; an optical fiber interferometer comprising: an optical fiber coupled to the light source; and an optical sensor comprising: a fiber-interface surface configured to be coupled to the optical fiber to receive broadband Gaussian light; a sensor body coupled to the fiber-interface surface such that at least a portion of light received by the fiber-interface surface will be reflected back to the optical fiber during use; and a binder-interface surface coupled to the sensor body, the binder-interface surface configurable to receive a chemical binder layer; and a high-resolution spectrometer coupled to the optical fiber interferometer to receive light reflected by the optical sensor, the spectrometer configured to detect interference between (i) light reflected from the fiber-interface surface of the optical sensor and (ii) light reflected from the binder-interface surface of the optical sensor.
