  Dark matter and dark energy are usually assumed to couple only
gravitationally. An extension to this picture is to model dark energy as a
scalar field coupled directly to cold dark matter. This coupling leads to new
physical effects, such as a fifth-force and a time-dependent dark matter
particle mass. In this work we examine the impact that coupling has on weak
lensing statistics by constructing realistic simulated weak-lensing maps using
raytracing techniques through N-body cosmological simulations. We construct
maps for different lensing quantities, covering a range of scales from a few
arcminutes to several degrees. The concordance $\Lambda$CDM model is compared
to different coupled dark energy models, described either by an exponential
scalar field potential (standard coupled dark energy scenario) or by a SUGRA
potential (bouncing model). We analyse several statistical quantities and our
results, with sources at low redshifts are largely consistent with previous
work on CMB lensing by Carbone et al., 2013. The most significant differences
from the $\Lambda$CDM model are due to the enhanced growth of the perturbations
and to the effective friction term in non-linear dynamics. For the most extreme
models, we see differences in the power spectra up to 40% compared to the
$\Lambda$CDM model. The different time evolution of the linear matter
overdensity can account for most of the differences, but when controlling for
this using a $\Lambda$CDM model having the same normalization, the overall
signal is smaller due to the effect of the friction term appearing in the
equation of motion for dark matter particles.
