Integrated dual-tomography for refractive index analysis of free-floating single living cell with isotropic superresolution

Abstract Digital holographic microtomography is a promising technique for three-dimensional (3D) measurement of the refractive index (RI) profiles of biological specimens. Measurement of the RI distribution of a free-floating single living cell with an isotropic superresolution had not previously be...
