The New Paradigm of Ligand Substitution-Driven Enhancement of Anisotropy from SO Units in Short-Wavelength Region.
ACS Cent Sci

For non-π-conjugated [SO] units, it is challenging to generate sufficient birefringence, owing to the high symmetry of the regular tetrahedron. Unlike the traditional trial-and-error approach, we propose a new paradigm for birefringence engineering to tune the optical properties based on [SO] units. Through the strategy of ligand substitution, we can predict its effect on the band gap and anisotropy.

View Article and Find Full Text PDFComputational Mueller matrix polarimetry holds great promise in biomedical studies and clinical applications, providing comprehensive polarization-related vectorial information within the sample. For backscattering polarization imaging systems aimed at in vivo tissue polarimetry, the measurement results can be affected by the Cartesian coordinates transformation due to the vectorial properties of polarized light and the non-collinear characteristics of the measurement system. It can influence the reliability of polarization information decoding and extraction.

- Fourier ptychography (FP) is a computational imaging technique that enhances image resolution and obtains phase information by using varied angles of light, but reconstructing images can be challenging, especially with noisy or incomplete data.
- To address these challenges, a new algorithm combining anisotropic total variation and Tikhonov regularizations is proposed, improving image reconstruction quality in high-throughput scenarios.
- The method, which utilizes the alternating direction method of multipliers, has been tested against other FP algorithms and shows promising results in noise reduction and preserving key details in images collected from biological specimens, even with sparse data.
