Brillouin Scattering Elastic Imaging for Lens in ex-vivo Porcine Eye (Invited)
Spontaneous Brillouin scattering detection system based on a dual-stage virtual imaging phase array (VIPA) spectrometer is proposed for elastic imaging of lens capsule and lens section of ex-vivo porcine eye. Results show that the Brillouin longitudinal elastic modulus of the porcine eye lens capsule is approximately 2.90 GPa at the equator and 2.84 GPa at the detect edge, and shows a gradual decrease from the equator toward the posterior pole. The Brillouin longitudinal elastic modulus of the porcine eye lens nucleus is about 3.72 GPa and is distributed in a plateau region at the center of the nucleus, it is about 3.32 GPa at the detect edge, and shows a gradual decrease from the lens nucleus to the surrounding cortical layers. Using Brillouin microscope to characterize the biomechanical properties of porcine eye lens, which is not only important for understanding the process of human eye regulation, but also can provide technical support for the diagnosis and treatment of human hyperopia.
