Paper Abstract

Optical diffraction tomography (ODT), which is one of the 3-D imaging techniques, enables non-invasive, label-free, and quantitative imaging of microscopic particles by retrieving multiple optical fields and reconstructing the 3-D hologram image of a sample. However, ODT employing the illumination scanning method suffers from poor axial resolution. In order to remedy this problem, we introduce TOmographic MOuld for optical TRAPping (TOMOTRAP) in ODT, which can control the orientation and shape of arbitrarily shaped dielectric objects. From optical field images of a sample rotated by several angles via TOMOTRAP, we reconstruct the 3-D RI distributions of samples with isotropic spatial resolution.
