Sub-Pixel Scale Structured Illumination for Lateral Resolution Enhancement of Non-Diffraction-Limited Flow Imaging
Hy Cao, Abhishek Saha, Lisa V. Poulikakos
In fluid flow imaging, intensity gradients are a good measure of spatial variations in scalar properties, which play an important role in controlling transport processes. However,…
Computational inverse design of acoustoplasmonic metasurfaces
Julia E. Holland, Nicholas Boechler, Lisa V. Poulikakos
Optical and acoustic metasurfaces are two-dimensional arrays of subwavelength elements that locally modulate or phase shift incident waves. Acoustoplasmonic metasurfaces combine th…
3D-architected gratings for polarization-sensitive, nature-inspired structural color
Moisés H. Ibarra Miranda, Lars W. Osterberg, Dev H. Shah +2
Structural coloration, a color-generation mechanism often found in nature, arises from light-matter interactions such as diffraction, interference and scattering, with micro- and n…
Leveraging Optical Anisotropy of the Morpho Butterfly Wing for Quantitative, Stain-Free, and Contact-Free Assessment of Biological Tissue Microstructures
Paula Kirya, Aida Mestre-Farrera, Jing Yang +1
Changes in the density and organization of fibrous biological tissues often accompany the progression of serious diseases ranging from fibrosis to neurodegenerative diseases, heart…
