AB  - Temperature measuring is a daily procedure carried out worldwide in practically 
      all environments of human activity, but it takes particular relevance in 
      industrial, scientific, medical, and food processing and production areas. The 
      characteristics and performance of the temperature sensors required for such a 
      large universe of applications have opened the opportunity for a comprehensive 
      range of technologies and architectures capable of fulfilling the sensitivity, 
      resolution, dynamic range, and response time demanded. In this work, a highly 
      sensitive fiber optic temperature sensor based on a double-cavity Fabry-Perot 
      interferometer (DCFPI) is proposed and demonstrated. Taking advantage of the 
      Vernier effect, we demonstrate that it is possible to improve the temperature 
      sensitivity exhibited by the polymer-capped fiber Fabry-Perot interferometer 
      (PCFPI) up to 39.8 nm/ degrees C. The DCFPI is sturdy, reconfigured, and simple to 
      fabricate, consisting of a semi-spherical polymer cap added to the surface of the 
      ferrule of a commercial single-mode fiber connector (SMF FC/PC) placed in front 
      of a mirror at a proper distance. The length of the air cavity (L(air)) was 
      adjusted to equal the thickness of the polymer cap (L(pol)) plus a distance delta to 
      generate the most convenient Vernier effect spectrum. The DCFPI was packaged in a 
      machined, movable mount that allows the adjustment of the air cavity length 
      easily but also protects the polymer cap and simplifies the manipulation of the 
      sensor head.
