The dielectric tensor is a physical quantity which characterizes birefringent materials with principal refractive indices and orientations of optic axes. Recently, three-dimensional dielectric tensor distribution was directly measured using dielectric tensor tomography (DTT). However, since the original DTT uses two cameras to acquire polarization-sensitive fields, position disagreement between the two fields deteriorates reconstruction quality. Here, we present multiplexed DTT using only one camera. To avoid the position disagreement, we exploit holographic multiplexing, interfering two orthogonally polarized reference beams with a sample beam on the camera. We validate the present method via measurement of anisotropic structures in liquid crystal particles.
