a Three phase-shifted frames of 2-μm polystyrene beads suspended in oil are imaged by spatial light interference microscopy (SLIM) using a ×63/1.4 NA objective. b The real part of the correlation function at three different time delays is obtained by solving Eq. (1). c 3D refractive index (RI) tomogram of the 2-μm polystyrene bead
