Dynamic spectro-polarimeter based on a modified Michelson interferometric scheme.

A simple dynamic spectro-polarimeter based on a modified Michelson interferometric scheme is described. The proposed system can extract a spectral Stokes vector of a transmissive anisotropic object. Detail theoretical background is derived and experiments are conducted to verify the feasibility of the proposed novel snapshot spectro-polarimeter.

Analysis of sinonasal anatomical variations associated with maxillary sinus fungal balls.

Objective: The pathogenesis of MSFB development remains unclear, but it has been suggested that poor sinus ventilation is associated with disease development; such a ventilation is influenced by anatomical variation of the paranasal sinuses. Thus, we sought to determine whether sinonasal anatomical variations were associated with MSFB development.

Methods: Thirty-one patients with MSFB and 28 gender-matched control patients were included in the present study.
