  We consider a generalized uncertainty principle (GUP) corresponding to a
deformation of the fundamental commutator obtained by adding a term quadratic
in the momentum. From this GUP, we compute corrections to the Unruh effect and
related Unruh temperature, by first following a heuristic derivation, and then
a more standard field theoretic calculation. In the limit of small
deformations, we recover the thermal character of the Unruh radiation.
Corrections to the temperature at first order in the deforming parameter are
compared for the two approaches, and found to be in agreement as for the
dependence on the cubic power of the acceleration of the reference frame. The
dependence of the shifted temperature on the frequency is also pointed out and
discussed.
