Measurements of flow-induced birefringence in microfluidics [PDF]
Biomicrofluidics, 2016 In this study, we demonstrate the use of a microscopic circular polariscope to measure the flow-induced birefringence in a microfluidic device that represents the kinematics of fluid motion optically. Unlike the commercial birefringence microscope employed in the previous studies, our approach is able to provide direct measurement of retardance, which ...

Measurement of the magnetic birefringence of noble gases [PDF]
Journal of the Optical Society of America B, 1984 The Cotton–Mouton constants of argon, krypton, and xenon have been measured relative to nitrogen at room temperature and ambient pressure for λ = 514.5 nm. Upper limits for helium and neon have been determined. The sensitivity of the apparatus was Δnmin = 0.8 × 10−14 for a measuring time of 1 sec.

Birefringent Glass‐Engraved Tilted Pillar Metasurfaces for High Power Laser Applications
Advanced Science, 2023 Birefringent materials—which are highly needed in high power laser systems—may be limited in usage due to the laser‐induced damage threshold of traditional birefringent materials.
