Bloch oscillations of atoms in optical lattices offer a powerful technique to significantly enhance the sensitivity of atom interferometers by orders of magnitude. To fully exploit the potential of this method, an accurate theoretical description of losses and phases beyond current treatments is essential. In this work, we expand the theoretical framework introduced by [Fitzek et al., arXiv:2306.09399] to three dimensions. We introduce multiple approaches to treat the transversal motion of atoms trapped in an accelerated optical lattice and investigate the influence of transversal effects on the interferometer. We compare our model to state-of-the-art atom interferometers, mainly [Panda et al., arXiv:2210.07289].
