摘要
We report on sizing spherical particles from far-field scattering light based on optical diffraction tomography. The distribution of the scattering potential, i.e. the distribution of the refractive index can be retrieved from an angular-resolved scattered field via an inverse Fourier transform. An algorithm based on this method was implemented and tested on a class of low-contrast particles. The results demonstrate that this method provides an accurate estimate of the particle size in the presence of moderate noise.
