A procedure for simulating the Mueller matrix of an optical system across the field of view of a long-wavelength infrared (LWIR) imaging polarimeter is presented in this paper. The procedure is based on a ray-tracing model and uses off-the-shelf software and custom add-on procedures written in MATLAB. A simulation was conducted to obtain polarization ray tracing across the entire surface of the focal-plane array for a set of wavelengths within the LWIR (8-14 µm) window and within the instrument's field of view of 7.3×5.5 with a set of different starting polarization states. Finally, the simulation results are compared with measurement data obtained from the home-designed optical train of a polarimetric camera. For Mueller matrix entries significantly larger than zero, both simulation and experiment results show high consistency, with overall RMS error of less than 2%. The presented results are useful when anticipation of a Mueller matrix of an imaging polarimeter is of high importance.

Characterization of retardance of nondepolarizing and depolarizing media.

A criterion for the characterization of the retardance effects produced by depolarizing and nondepolarizing linear media on interacting light is established based on Mueller matrices algebra. A consistent general description of retardance properties is performed by means of a serial decomposition of the Mueller matrix into three components, namely an element that encompasses the enpolarizing and depolarizing properties sandwiched by two elliptical retarders containing complete and decoupled information on retardance. The inherent ambiguity derived from the coincident formal structure of rotation matrices and circular retarders is removed though the introduction of the entrance and exit intrinsic reference frames, leading to the concepts of the intrinsic entrance and exit linear retarders, which are defined from the Mueller matrix itself and that are independent of the laboratory reference frames used to represent the incident and emerging polarized light beams, respectively.

The development of chiral organic materials with strong non-reciprocal chiroptical features may have major implications for cutting-edge technological applications. In this work, a new synthesized chiral 1,4-diketo-3,6-dithienylpyrrolo[3,4-]pyrrole dye, bearing two ()-3,7-dimethyl-1-octyl alkyl chains on the lactam moieties and functionalized with two lateral 9-anthracenyl π-conjugated units, exhibited strong non-reciprocal chiroptical properties in thin films, with some important differences between samples prepared by drop casting and spin coating. A detailed study was performed to unravel the intimate structure-property relationship, involving computational analysis, different microscopy techniques and synchrotron radiation Mueller matrix polarimetry imaging (SR-MMP) investigation.

A clinical isolate, R131, was isolated from the peritoneal swab of a patient who suffered from ruptured appendicitis with abscess and gangrene in Hong Kong in 2018. Cells are facultatively anaerobic, non-motile, Gram-positive coccobacilli. Colonies were small, grey, semi-translucent, low convex and alpha-haemolytic.
