Strong lensing systems and galaxy cluster observations as probe to the
  cosmic distance duality relation
  {In this paper, we use large scale structure observations to test the
redshift dependence of cosmic distance duality relation (CDDR), $D_{\rm
L}(1+z)^{-2}/D_{\rm A}=\eta(z)$}, with $D_{\rm L}$ and $D_{\rm A}$, being the
luminosity and angular diameter distances, respectively. In order to perform
the test, the following data set are considered: strong lensing systems and
galaxy cluster measurements (gas mass fractions). No specific cosmological
model is adopted, only a flat universe is assumed. { By considering two
$\eta(z)$ parametrizations, It is observed that the CDDR remain redshift
independent within $1.5\sigma$ which is in full agreement with other recent
tests involving cosmological data}. It is worth to comment that our results are
independent of the baryon budget of galaxy clusters.
