We present a case of Brugada syndrome associated with augmentation of multiple J waves and the presence of “pseudo-epsilon” wiggle waves in the lateral leads. Just after ventricular fibrillation (VF), J waves were prominent in leads V1 through V4

The concept of ensemble-average polarization and coherence has been applied to studying fluctuating Stokes parameters in a polarization speckle observed when coherent light is passed through a birefringent polarization scrambler. With the aid of the

Publikováno v: Optics letters. 47(5)

A method is proposed for 3D imaging through a highly heterogeneous double-composite random medium made of a thick mildly inhomogeneous medium followed by a thin strongly scattering layer. To realize the immunity to the heterogeneous random medium, a

Performance analysis for a polarization imaging system with rotational alignment errors from polarizing elements

Autor: Mitsuo Takeda, Shengzhu Xiao, Jianlin Nie, Wei Wang

Publikováno v: Computational Optics 2021.

In this paper, we give a spatial frequency analysis of polarization imaging system and study the effects of rotational alignment errors of the polarizer from their ideal orientations. With the help of newly proposed Optical Transfer Matrix (OTM) for
