This paper presents an erbium-doped fiber laser temperature sensor, which is based on an intracavity fiber filter immersed in glycerol/water solutions. The sensing element is the intracavity fiber filter, consisting of a two-taper fiber Mach-Zehnder

It is quite common that patients with ligamentous ruptures, tendonitis, tenosynovitis or sprains are foreseen the use of ad hoc splints for a swift recovery. In this paper, we propose a rehabilitation split that is focused on upper-limb injuries. By

In this paper, a cubic-like structure is proposed to scan and print tools used as medical equipment at low cost for developing countries. The structure features a 3-axis frame plane that uses high-precision step motors. An actuator drives the “x an

We present a numerical analysis of the response of arc-induced long-period fiber gratings (LPFGs) under ambient refractive-index changes using standard fibers with SiO2 as cladding material and different GeO2 concentration in the SiO2-GeO2 doped core

A highly sensitive curvature and displacement sensing arrangement based on an all optical fiber micro Fabry–Perot Interferometer (MFPI) is presented. Here, the MFPI spectral fringes contrast is decreased due to curvature effects occurring within a

We show a tunable multimode-interference filter based on a Yb-doped fiber. The filter is tuned up to 3.2 nm modifying the gain of the Yb-doped fiber, and has a temperature sensitivity of 0.22nm/°C.

We present an experimental characterization of a fiber laser composed by an Yb-doped fiber spliced with a birrefringent photonic crystal fiber and a mechanically-induced long-period grating (LPG) into the laser cavity. According to the torsion proper
