Determination of cell elasticity through hybrid ray optics and continuum mechanics modeling of cell deformation in the optical stretcher

The optical stretcher is a dual-beam trap capable of stretching individual cells. Previous studies have used either ray- or wave-optical models to compute the optical pressure on the surface of a spherical cell. We have extended the ray-optics model to account for focusing by the spherical interface...
