Analysis of polarization characteristics of freeform surface optical system [PDF]

ITM Web of Conferences, 2022
Freeform surfaces are widely used in off-axis optical systems with large aperture, large field of view, and long focal length. The polarization effect caused by the non-rotationally symmetrical shape has an impact on the system’s polarization imaging ...

Spun fibers and their description within the Jones formalism in analyzing the practical fiberoptic circuits

St. Petersburg Polytechnical University Journal: Physics and Mathematics, 2023
In this paper, an analytical form for the Jones matrix of a real spun fiber has been obtained, taking into account a slight deviation of its properties from an idealized representation of this fiber by the rotation matrix.

Polarization Domain Spectrum Sensing Algorithm Based on AlexNet

Sensors, 2022
In this paper, we propose a spectrum sensing algorithm based on the Jones vector covariance matrix (JCM) and AlexNet model, i.e., the JCM-AlexNet algorithm, by taking advantage of the different state characteristics of the signal and noise in the ...

A Parsimonious Test of Constancy of a Positive Definite Correlation Matrix in a Multivariate Time-Varying GARCH Model

Econometrics, 2022
We construct a parsimonious test of constancy of the correlation matrix in the multivariate conditional correlation GARCH model, where the GARCH equations are time-varying. The alternative to constancy is that the correlations change deterministically as
