Abstract

The stiffness of biological tissues could be assessed by measuring the propagation of mechanically induced waves on its surfaces that could help identifying various tissue pathologies. Here we present results for the volumetric assessment of mechanical waves propagating on both surfaces of the crystalline lens measured with the Phase-Sensitive Swept Source Optical Coherence Tomography (PhS-SSOCT) technique. The results indicate that the system could detect vibrations of as small as 0.03 μm in amplitude induced on the surface of crystalline lens, and hence, PhS-SSOCT could potentially be used to assess stiffness of a crystalline lens.
