[en] cosmic mirage ; gravitational lens ; lens inversion ; multiply imaged quasars
[en] Given an observed gravitational lens mirage produced by a foreground deflector (cf.
galaxy, quasar, cluster, . . . ), it is possible via numerical lens inversion to retrieve the real
source image, taking full advantage of the magnifying power of the cosmic lens. This
has been achieved in the past for several remarkable gravitational lens systems. Instead,
we propose here to invert an observed multiply imaged source directly at the telescope
using an ad-hoc optical instrument which is described in the present paper. Compared
to the previous method, this should allow one to detect fainter source features as well
as to use such an optimal gravitational lens telescope to explore even fainter objects
located behind and near the lens. Laboratory and numerical experiments illustrate this
new approach.
