Let $X = {X(t), t ∈ ℝ^{N}}$ be a Gaussian random field in $ℝ^{d}$ with stationary increments. For any Borel set $E ⊂ ℝ^{N}$, we provide sufficient conditions for the image X(E) to be a Salem set or to have interior points by studying the asymptotic properties of the Fourier transform of the occupation measure of X and the continuity of the local times of X on E, respectively. Our results extend and improve the previous theorems of Pitt [24] and Kahane [12,13] for fractional Brownian motion.
