Abstract

The vitreous humor of the eye is modelled as a homogeneous viscoelastic sphere. The analysis provides a relation for the displacement amplitude and phase following oscillatory and step excitations, as functions of the storage and loss moduli of the vitreous gel, and allows calculation of the resolution requirements for a non-invasive optically-based diagnostic method for the viscoelastic properties of the vitreous.

摘要

眼睛的玻璃体被建模为一个均匀的粘弹性球体。该分析给出了在振荡激励和阶跃激励后位移幅度和相位的关系，作为玻璃体凝胶储能模量和损耗模量的函数，并允许计算基于光学的玻璃体粘弹性特性非侵入性诊断方法的分辨率要求。
