This article presents a reflective Fabry–Perot (FP) dual-parameter sensor utilizing nematic liquid crystal (LC) for high-sensitivity temperature and magnetic field measurement. The FP interferometer is comprised an incident single-mode fiber with flat-cut end, reflection flat end silver coated. cascaded Bragg grating (FBG). LCs are injected into the cavity. All of structures packaged in capillary tube to construct sensor. Due directional nature LC molecules, they sensitive fields....
A new iterative algorithm to be used precisely reconstruct near-field distribution from an interferogram of a laser output generated by cyclic radial-shearing interferometer is proposed. First, use window function around the zero-frequency part Fourier transform and calculation inverse part, we obtain background intensity interferogram. Then, according algorithm, reconstructed obtained in first step. numerical simulation actual experiment reconstruction with arbitrary amplitude are...
A temperature-insensitive electric field sensor utilizing HF-etched tilted gratings in a high refractive index solution (E 7 liquid crystal) is proposed. The causes change the original arrangement of molecules, thereby altering crystals. This study demonstrates that combination crystal and effectively excites cladding leakage mode grating. Compared to non-etched fiber Bragg grating, proposed exhibits higher sensitivity fields. experimental results show grating with diameter 17.7 µm 0.024...
With the development of optical fiber communications, especially maturity amplifiers and WDM technology, space communication at 1550 nm becomes a promising solution for future high speed satellite communication. Receiving technology with coupling light into single mode are key technologies in nm. Free-space-to-fiber technique investigated this paper is first challenge applying techniques to free communications. We analyzed factors that affect efficiency free-space-to single-mode-fiber based...
Space laser communication is moving in a wider bandwidth, greater distances, more accurate and narrow beam direction, faster bandwidth as well interface chip high-speed clock demanding requirements of the low frequency noise, good reliability, small size power consumption characteristics. Production ADI's ADF4350 integrated voltage-controlled oscillator (VCO) synthesizer just to meet this requirement This paper describes basic principles operating characteristics broadband synthesizer. In we...

This paper states how...
This study introduces a temperature sensing mechanism of heightened sensitivity through the evaluation fringe visibility and Vernier effect within an FBG-FP (Fiber Bragg Grating - Fabry-Perot) setup. By amalgamating two cleaved single-mode fibers (SMFs) capillary tube, FP microcavity is crafted. Notably, one extremity SMF affixed with silver coating to bolster reflectivity. The infusion liquid crystal (LC) materials into cavity birefringence, thus catalyzing emergence phenomenon....
