  The optical analogue of quantum weak measurements have shown considerable
promise for the amplification and observation of tiny optical beam shifts,
namely, the Goos-H\"anchen (GH) and the Imbert-Fedorov (IF) shifts. Here, we
demonstrate simultaneous weak value amplification of both the angular GH and
the IF shifts in partial reflection of fundamental Gaussian beam at planar
dielectric interfaces. We employ pre- and post selection schemes with
appropriate linear polarization basis states for simultaneous weak measurements
and amplification of both these shifts. The experimentally observed enhancement
of the beam shifts and their dependence on the angle of incidence are analyzed
/ interpreted via quantum mechanical treatment of weak measurements.
