Flexible and stable demodulation techniques of large-scale fiber-optic Fabry–Perot (FP)
acoustic sensors are highly desirable for accelerating their industrial applications. In this …

We present a frequency-sweeping heterodyne interferometer to measure an absolute
distance based on a frequency-tunable diode laser calibrated by an optical frequency comb …

A picometer resolution Fabry–Perot (F–P) interferometer is proposed. The Pound–Drever–
Hall locking scheme is employed to lock the frequency of a tracking external cavity diode …

Temperature distributions of dynamical flames were measured by using a proposed
calibration-free wavelength modulated lateral shearing interferometry. A distributed …

Continuously and widely tunable lasers, actively stabilized on a frequency reference, are
broadly employed in atomic, molecular, and optical (AMO) physics. The frequency-stabilized …

In this paper, the optical fiber Fabry–Perot (FP) interferometer based on phase-shifting
technique and birefringence crystals is proposed and demonstrated. We use the …

A parameter fitting-based fast imaging method for axisymmetric flame temperature field was
proposed in a lateral shearing interferometer. In the extinction state, a sawtooth waveform …

To determine the absolute diameter of a silicon sphere for the Avogadro constant project, we
present a phase-shifting interferometer based on a flat etalon and a traceable single laser …

We conduct a theoretical and experimental analysis for a self-referencing phase-locked
module based on the delay-unbalanced Mach-Zehnder interferometer (UMZI) and optical …
