There are lots of things like ﬁber laser strain, wavelength division, strain measurement, single mode laser, strain sensor device, optical, ﬁber laser, intensity, strain amplitude, opto electronic, intensity noise, sensor system, output, the time domain, temperature, and frequencies are described inside this paper. The paper presents information like amplitude, interferometer, time domain, optical ﬁber, noise, laser, fft spectrum analyzer, cavity, frequency, strain, wavelength, time constant, responsivity, laser strain, sinusoidal, and optic.
Inside this paper the reader can find information like sensor, radio frequency modulation, voltage, sensors, sensitivity, pressure temperature, fiber laser strain, sinusoidal strain, diode laser, wavelength division multiplexer, feedback loop, low pass ﬁltering, thermal phase ﬂuctuations, mzi output intensity, remote, and interferometric. The following are excerpted from this paper:
We present a ﬁber laser strain sensor (FLSS) with noise-equivalent sensitivity equal to or better than 80 pεrms (Hz)−1/2 at very low frequencies, from 100 mHz to several hundreds of hertz. The strain affects the ﬁber laser emission wavelength, and an imbalanced Mach–Zender interferometer (MZI) converts wavelength variations into phase-amplitude variations. The sensor has been also tested in the time domain by applying sinusoidal strain bursts: the device also shows a good signal-to-noise ratio at the lowest burst frequencies.
Furthermore, the paper contains more things like ﬁber, acoustic noise, radiation, the ﬁber laser, strain sensor, signal, measurement, laser strain sensor, low pass ﬁlter, photo detection, strain frequency, balanced photo detection, opto electronic servo, spectrum, and the opto electronic.
