Abstract:
Various embodiments provide an optical sensor having an optical source, a grating arrangement optically coupled to the optical source to receive a source optical signal from the optical source, the grating arrangement including a chirped FBG having a defined spectral profile, wherein, in response to a first change in at least one parameter interacting with the chirped FBG, the defined spectral profile is shifted in a first direction relative to a reference spectral profile, and the grating arrangement is configured, in response thereto, to generate a first output optical signal corresponding to the first change, and wherein, in response to a second change in the at least one parameter interacting with the chirped FBG, the defined spectral profile is shifted in a second direction relative to the reference spectral profile, and the grating arrangement is configured, in response thereto, to generate a second output optical signal corresponding to the second change.

Claim (Index 4):
The optical sensor as claimed in  claim 3 , wherein the grating arrangement further comprises:\n a third chirped FBG having a second defined spectral profile; and a fourth chirped FBG configured to provide a second reference spectral profile, the fourth chirped FBG being optically coupled to the third chirped FBG, wherein the second defined spectral profile at an original state of the third chirped FBG and the second reference spectral profile are shifted relative to each other in wavelength, wherein the third chirped FBG is configured, in response to a third change in a parameter interacting with the third chirped FBG, to change from the original state to a third state to shift the second defined spectral profile in a third direction relative to the second reference spectral profile and, further configured to generate a third reflected optical signal in response to the second defined spectral profile being shifted in the third direction, and wherein the fourth chirped FBG is configured to transmit, based on the second reference spectral profile, a portion of the third reflected optical signal as a third output optical signal corresponding to the third change, and wherein the third chirped FBG is configured, in response to a fourth change in the parameter interacting with the third chirped FBG, to change from the original state to a fourth state to shift the second defined spectral profile in a fourth direction relative to the second reference spectral profile, and, further configured to generate a fourth reflected optical signal in response to the second defined spectral profile being shifted in the fourth direction, and wherein the fourth chirped FBG is configured to transmit, based on the second reference spectral profile, a portion of the fourth reflected optical signal as a fourth output optical signal corresponding to the fourth change.
