This study proposed a self-compensation three-wavelength demodulation method for
interrogating fiber-optic extrinsic Fabry–Pérot interferometric (EFPI) sensors. The variation in …

Apparatus is provided for diagnosing or treating an organ or vessel, wherein a deformable
body having at least two optical fiber sensors disposed in a distal extremity thereof is …

Apparatus is provided for diagnosing or treating an organ or vessel, wherein a device
having at least two optical fiber sensors disposed in a distal extremity thereof is coupled to …

A catheter for diagnosis or treatment of a vessel or organ is provided in which a flexible
elongated body includes a tri-axial force sensor formed of a housing and a plurality of optical …

A novel miniature fiber-optic Fabry-Perot (FP) refractive-index (RI) sensor machined by 157
nm laser is proposed. The sensor head consists of a micro air FP cavity near the tip of a …

A touch sensing catheter having a strain sensor assembly that may resolve the magnitude
and direction of a force exerted on a distal extremity of the catheter, the strain sensor …

A novel and low cost fiber-optic extrinsic Fabry–Perot interferometer (EFPI) is proposed. The
EFPI is fabricated at the fiber tip by inserting a single mode fiber (SMF) into a partially …

This paper presents a high-sensitivity, all-silica, all-fiber Fabry-Perot strain-sensor. The
proposed sensor provides a long active length, arbitrary length of Fabry-Perot cavity, and …

In this paper, we discuss the design, fabrication, and testing of an external Fabry–Perot
interferometer (EFPI)-based absolute type fiber optic pressure sensor of range 0–50 mbar …

This paper presents an in-line, short cavity Fabry-Perot fiber optic strain sensor. A short air
cavity inside a single-mode fiber is created by the fusion splicing of appropriately micro …
