摘要：
The disclosure includes an apparatus for insertion into a body lumen. The apparatus can comprise an optical fiber pressure sensor. The optical fiber pressure sensor can comprise an optical fiber configured to transmit an optical sensing signal. A temperature compensated Fiber Bragg Grating (FBG) interferometer can be in optical communication with the optical fiber. The FBG interferometer can be configured to receive a pressure and modulate, in response to the received pressure, the optical sensing signal. A compliant member such as a sensor membrane can be in physical communication with the FBG interferometer. The membrane configured to transmit the received pressure to the FBG interferometer.
