We present a high-resolution and large dynamic range-phase-shifted fiber Bragg grating (-
PSFBG) temperature sensor. A current modulated laser diode with a linearized optical …

In this work, we investigated the frequency stabilization method of a diode laser that
operates on the excited state transition 5P\to 5D of Rb atoms. The described technique …

We investigate the relative intensity noise (RIN) properties of a multi-Stokes Brillouin fiber
ring laser. We experimentally analyse the intensity noise of each Stokes wave and study the …

Nous décrivons ici un amplificateur synchrone à faible coût que l'on peut construire en
utilisant des composantes RF couramment disponibles et des circuits analogues faits …

Lock-in amplifiers are used to process the analog signals even in the presence of noise
sources of greater amplitude. In the present study, an attempt is made to design a …

We propose a precise method for optical frequency shifting with high signal-to-noise ratio
based on stimulated Brillouin scattering (SBS). The lower sideband of the intensity …

Lock-in amplifiers are a powerful tool for signal detection within a noise environment.
Commercial Lock-in amplifiers are bulky and disqualified for handheld operation. We report …

Pushing the RV technique to the precision required to detect Earth-like planets around Solar-
type stars requires extreme stability in the wavelength calibrator. We are developing a …

In this paper, the Xilinx Artix-7 FPGA chip was used as the processor to submit an
orthogonality cross correlation algorithm with strong anti-interference capacity that …
