Abstract
In this paper, we present a compressive and complete mathematical description of the photonics force distribution on a spherical cell surface in optical stretcher. Using the ray tracing model, we demonstrate that the forces are always perpendicular to the surface and describe the apparition of a peak and a discontinuity in the force distribution that was not previously revealed. Besides, we present a better approximate fitting of the stress distribution by polynomials of powers of cosines as a function of physical parameters and the ratio between the FWHM of the Gaussian beam and the cell's radius. The fitting of the force distribution is required for analyzing the cell's deformation.
