P. 312–315.
This paper analyzes the main factors affecting the accuracy of recording the movement of an object using an amplitude fiber optical sensor with external modulation of the radiation flux is analyzed. The structural scheme, the operating principle and the algorithm for processing the measuring information of a non-contact infrared sensor for recording the moment of passage of a reflective mark are given. The variants of using the developed sensor in the monitoring systems of technological equipment are considered.

We propose a new cryothermal setup for testing and comparison fiber optic tilt sensors in extremely-low temperature conditions. The setup makes possible simulating the required temperature conditions, investigating fiber optic tilt sensors accuracy characteristics and tracing trends of the sensors operation when ambient temperature decreases to critical low values. ...

Tilted fiber Bragg gratings (TFBGs) possess promising characteristics for refractometric purposes. However, their
complex spectral response containing a large number of features makes the sensor’s output relevance highly
dependent on data demodulation and interpretation. We propose a method for processing sensor data based on a
detailed analysis of the system’s behavior during the transition of cladding modes from ...

Fluorescence imaging of single quantum light emitters (atoms, molecules, quantum dots, color centers in crystals)
is an inherent experimental problem of modern photonics and its numerous applications. In these measurements,
highly sensitive cameras are of the key significance. Recent progress in technologies of chargecoupling
devices (CCD) and complementary metal-oxide semiconductor (CMOS) sensors opens up possibilities
for detection of extreme ...

We experimentally demonstrate a quantum receiver based on the Kennedy scheme for discrimination between two phase-modulated weak coherent states. The receiver is assembled entirely from standard fiber-optic elements and operates at a conventional telecom wavelength of 1.55 μm. The local oscillator and the signal are transmitted through different optical fibers, and the displaced signal is ...

We propose an all-dielectric magneto-photonic crystal with a hybrid magneto-optical
response that allows for the simultaneous measurements of the surface and bulk refractive index of
the analyzed substance. The approach is based on two different spectral features of the magnetooptical
response corresponding to the resonances in p- and s-polarizations of the incident light.
Angular spectra of p-polarized light have ...

It is shown that tailored breaking of the translational symmetry through weak scattering in waveguides and optical fibers can control chromatic dispersions of the individual modes at any order; thereby, it overcomes the problem of coherent classical and quantum signal transmission at long distances. The methodology is based on previously developed quantum control techniques and ...

Perspective methods of information transfer in optical communication channels based on the latest achievements of quantum physics are considered. In the near future these methods can solve both the problem of creating an optical channel conducting with physically unlimited bandwidth, and the problem of secretly transferring information in a fiber-optic information channel. The results of ...

The article describes new method of use after free bug detection using program dynamic analysis. In memory-unsafe programming languages such as C/C++ this class of bugs mainly accurse when program tries to access specific area of dynamically allocated memory that has been already freed. This method is based on combination of two basic components. The ...

The behavior of the TE and TM electromagnetic waves in graphene at the interface between two semi-infinite dielectric media is studied. The dramatic influence on the TE waves propagation even at very small changes in the optical contrast between the two dielectric media is predicted. Frequencies of the TE waves are found to lie only ...
