Dynamic Sensor Interrogation Using Wavelength-Swept Laser with a Polygon-Scanner-Based Wavelength Filter
We report a high-speed (~2 kHz) dynamic multiplexed fiber Bragg grating (FBG) sensor interrogation using a wavelength-swept laser (WSL) with a polygon-scanner-based wavelength filter. The scanning frequency of the WSL is 18 kHz, and the 10 dB scanning bandwidth is more than 90 nm around a center wavelength of 1,540 nm. The output from the WSL is coupled into the multiplexed FBG array, which con...
متن کاملHigh-speed wavelength-swept semiconductor laser with a polygon-scanner-based wavelength filter.
Ultrahigh-speed tuning of an extended-cavity semiconductor laser is demonstrated. The laser resonator comprises a unidirectional fiber-optic ring, a semiconductor optical amplifier as the gain medium, and a novel scanning filter based on a polygonal scanner. Variable tuning rates up to 1150 nm/ms (15.7-kHz repetition frequency) are demonstrated over a 70-nm wavelength span centered at 1.32 micr...
متن کاملCharacterization of FBG sensor interrogation based on a FDML wavelength swept laser.
In this study, we develop an ultra-fast fiber Bragg grating sensor system that is based on the Fourier domain mode-locked (FDML) swept laser. A FDML wavelength swept laser has many advantages compared to the conventional wavelength swept laser source, such as high-speed interrogation, narrow spectral sensitivity, and high phase stability. The newly developed FDML wavelength swept laser shows a ...
متن کاملInterrogation of fiber grating sensor arrays with a wavelength-swept fiber laser.
We demonstrate a novel application of a wavelength-swept fiber laser to fiber Bragg grating sensor-array interrogation. The laser provides high signal powers of >3 mW with <0.1-nm spectral resolution over a 28-nm wavelength span. Using time-interval counting, we demonstrate static-dynamic strain measurements with a resolution of 0.47mu? rms at a sampling rate of 250 Hz.
متن کاملHigh-speed polygon-scanner-based wavelength-swept laser source in the telescope-less configurations with application in optical coherence tomography.
A compact high-speed tuning laser source is demonstrated in two different configurations using a polygonal mirror scanner without a telescope. It is shown that the filter configuration finesse increases by utilizing multiple reflections from the polygon facet(s) and grating illumination(s). Theoretically, the free spectral range (FSR), the instantaneous linewidth, and the finesse of each filter...
