“…The three dimensional cosmic shear [22][23][24] seems to be a promising observable that can be measured by weak lensing observations. Currently, the observations are mostly two dimensional [25][26][27] with preliminary studies of 3D analysis [28,29] and future programs expected to have three dimensional capabilities [30,31]. The recent advances in measuring the cosmic shear and the expected future improvements have attracted a growing interest in the potential of weak lensing measurements for determining the expansion history of the universe, either by itself [32][33][34][35][36] or in combination with other measurements [37][38][39].…”

We study the functional dependence of the spin-weighted angular moments of the two-point correlation function of the three dimensional cosmic shear on the expansion history of the universe. We first express the redshift dependent total equation of state parameter in terms of the growing mode of the gauge invariant metric perturbation in the conformal-Newtonian gauge for the case of adiabatic perturbations. We then express the redshift dependent angular moments of the shear two-point correlation function as an integral in terms of the metric perturbation. We present the final explicit expression for the case of a Harrison-Zeldovich spectrum of primordial perturbations. Our analysis is restricted to the linear regime. We use our results to make a preliminary study of the required sensitivity that will allow cosmic shear observations to add significant information about the expansion history of the universe.
