20.500.12556/DKUM-91761 A short-range quasi-distributed strain and temperature sensing system utilizing a standard telecom laser diode 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 proper sensor geometry selection provides the possibility for a high-resolution spectral interrogation of the sensing array while relying on an ordinary, cost-effective distributed feedback (DFB) telecom laser diode. Beside the telecom DFB diode, the entire interrogation system includes only an additional detector, optical coupler, analog interface and a microcontroller. Measurement resolution better than 1 µε was demonstrated experimentally at a sampling rate exceeding 65 samples per second, while utilizing a sensing device with a typical length of 50 mm and spatial resolution of approximately 2 mm. To demonstrate the application potential of the proposed measuring device, a few different packages and sensor configurations were demonstrated and tested, including a system for tactile sensing applications and a short-range quasi-distributed temperature measurement probe. optical fiber sensors short-range quasi-distributed fiber-optic sensor strain/temperature sensing device cost-effective interrogation system tactile sensing phase subtraction optična vlakna optični senzorji senzorji true false true Elsevier Angleški jezik Slovenski jezik https://www.sciencedirect.com/journal/optics-and-laser-technology © 2024 The Author(s) Članek v reviji 2025-02-03 13:50:34 2025-02-03 13:50:34 2026-01-19 08:00:13 0000-00-00 00:00:00 2025 0 0 12 str.
