This paper describes a Fabry–Pérot sensor-based measuring system for measuring fluid composition in demanding industrial applications. The design of the sensor is based on a two-parametric sensor, which enables the simultaneous measurement of temperature and refractive index (RI). The system Read More …
This article presents an all-fiber, miniature Fabry-Perot gas sensor based on photothermal absorption spectroscopy with a custom-made and cost-efficient interrogation system. The sensing gas microcell has a diameter of 125 μ m and a length of 1 mm, and allows for Read More …
This work presents a compact fiber-integrated sensor designed for high-resolution measurement of electric currents and magnetic fields using a magneto-optic liquid microcell. The primary goal is to develop a miniature, customizable sensor capable of operating in challenging environments where electrical Read More …
This paper presents a miniature, dual-axis, widely tunable fiber-optic accelerometer based on a four-core fiber mechanically coupled to an inertial mass by the superelastic NiTi microwire. The proposed structure forms a compact spring–damper system with an adjustable eigenfrequency and acceleration Read More …
This paper presents an all-silica microwire optical sensor designed for both fast response time and high-resolution temperature detection. The sensor consists of a thin optical microwire created at the tip of an optical fiber, configured as a temperature sensitive Fabry-Perot Read More …
This article presents a short-range fiber-optic quasi-distributed sensing device suitable for strain and temperature measurement. The sensing assembly consists of an fs laser inscribed reference mirror and a sensing array of equidistantly positioned mirrors. Utilization of the reference mirror and Read More …

This paper reports on nano-strain resolution fiber-optic Fabry-Perot sensors produced by an improved selective etching method. The presented sensors exhibit high spectral sensitivity, low intrinsic temperature response, small size and mounting comparable to conventional Fiber Bragg gratings. Furthermore, the proposed Read More …
A light-driven micromechanical oscillator is presented, which can be operated by a low optical power (in the mW, or even the µW range), can produce large mechanical displacements (>5–100 µm), and can be designed to operate at frequencies from sub-kHz up Read More …
The deposition rates of protective coatings resembling polydimethylsiloxane (PDMS) were measured with numerous sensors placed at different positions on the walls of a plasma-enhanced chemical vapor deposition (PECVD) reactor with a volume of approximately 5 m3. The plasma was maintained Read More …
