  We investigate laboratory tests of dark energy theories which modify gravity
in a way generalising the inverse power law chameleon models. We make use of
the tomographic description of such theories which captures $f(R)$ models in
the large curvature limit, the dilaton and the symmetron. We consider their
effects in various experiments where the presence of a new scalar interaction
may be uncovered. More precisely, we focus on the Casimir, Eot-wash and neutron
experiments. We show that dilatons, symmetrons and generalised chameleon models
are efficiently testable in the laboratory. For generalised chameleons, we
revise their status in the light of forthcoming Casimir experiments like CANNEX
in Amsterdam and show that they are within reach of detection.
