Mueller Matrix Ellipsometric Approach on the Imaging of Sub-Wavelength Nanostructures
Frontiers in Physics, 2022 Conventional spectroscopic ellipsometry is a powerful tool in optical metrology. However, when it comes to the characterization of non-periodic nanostructures or structured fields that are much smaller than the illumination spot size, it is not well ...

Snapshot retinal imaging Mueller matrix polarimeter [PDF]
SPIE Proceedings, 2015 Early diagnosis of glaucoma, which is a leading cause for visual impairment, is critical for successful treatment. It has been shown that Imaging polarimetry has advantages in early detection of structural changes in the retina. Here, we theoretically and experimentally present a snapshot Mueller Matrix Polarimeter fundus camera, which has the ...
