Three-dimensional polarization probing in polymer ferroelectrics, polymer-dispersed liquid crystals, and polymer ferroelectrets
… three-dimensional images of electric field and polarization distribution in a material. This thermal technique use a pulsed heating by means of focused laser light which is absorbed by opaque electrodes. The diffusion of the heat causes changes in the sample geometry, generating a short-circuit …

Radio-polarimetric observations of gravitational lenses
… and the general-relativistic invariance of polarization under lensing. We performed high dynamic-range VLBI imaging polarimetry of the gravitational lens system B0218+357 at 43 GHz, and further VLBI observations of this system in the frequency range 8 GHz - 43 GHz. Further analysis included …

Quantitative anisotropy imaging with polarized interference microscopy
… have been developed, such as fluorescence polarization microscopy(FPM), liquid crystal based polarization microscopy (LC Polscope), polarization state optical coherence tomography (ps OCT), and polarization Raman spectroscopy. Quantitative phase microscopy (QPM) is another important …

Diffusionsgekühlte, koaxiale CO 2 -Laser mit hoher Strahlqualität
… in all directions. The essentially azimuthal polarization distribution of the beam emitting from the helix-axicon resonator remains during the forming in the telescope and results in a space-wise varying polarization direction over the beam expansion. Possibilities for the transformation into …

Second-harmonic generation-based Mueller matrix polarization analysis of collagen-rich tissues
… tissue microstructure is the Mueller matrix polarization response. Two polarimetric imaging approaches are demonstrated for robust Mueller matrix characterization of collagenous tissue. One approach, called the two-photon Mueller matrix second-harmonic generation (MMSHG) microscopy, involves …
