This research presentation showcases the development of a polarization-based imaging system for quantifying collagen fiber orientation in heart valve tissue during biaxial mechanical testing.
Sponsored by Prof. Chung-Hao Lee at the University of Oklahoma, this capstone project demonstrates how rotating polarizers and polarization-dependent light reflection can be used to dynamically map collagen fiber orientation while tissue is mechanically loaded.
When paired with a biaxial testing system, this modular imaging approach enables real-time visualization of microstructural changes in fibrous soft tissues, supporting advanced research in heart valve biomechanics and constitutive modeling.
