EVALUATION METHOD FOR PARASITIC EFFECTS OF THE ELECTRO-OPTICAL MODULATOR IN A FIBER OPTIC GYROSCOPE [PDF]
Научно-технический вестник информационных технологий, механики и оптики, 2016 Subject of Research.The paper proposes an original method for studying the parasitic effects in the electro-optic modulator of the fiber optic gyroscope. Proposed method is based on the usage of a special waveform phase modulation signal. Method.

Measuring the Reflection Matrix of a Rough Surface
Applied Sciences, 2017 Phase modulation methods for imaging around corners with reflectively scattered light required illumination of the occluded scene with a light source either in the scene or with direct line of sight to the scene. The RM (reflection matrix) allows control

Performance Optimization of SNR and SFDR in RoF Link for the Next Generation Networks
The Journal of EngineeringA radio frequency over fibre (RFoF) or radio over fibre is a versatile technology, in which light is modulated with radio frequency signal and an optical fibre link is used as a medium to transmit it.

Reciprocal control of viral infection and phosphoinositide dynamics
FEBS Letters, EarlyView.Phosphoinositides, although scarce, regulate key cellular processes, including membrane dynamics and signaling. Viruses exploit these lipids to support their entry, replication, assembly, and egress. The central role of phosphoinositides in infection highlights phosphoinositide metabolism as a promising antiviral target.

Spin-Selected Dual-Wavelength Plasmonic Metalenses
Nanomaterials, 2019 Several novel spin-selected dual-wavelength metalenses have been proposed and investigated based on the plasmonic metasurface consisting of two kinds of rotary rectangle gap nanoantennas (RGN), which are designed based on merging two or four polarity ...

Rotating vortex imaging implemented by a quantized spiral phase modulation [PDF]
Journal of the European Optical Society-Rapid Publications, 2013 We demonstrate both theoretically and experimentally that a spiral mask with a finite number of discrete phase levels allows a defocusing induced rotation of the point spread function in the vortex imaging.
