Abstract
Here we present a direct observation of the Gouy effect through THz impulse scattering from cylindrical and spherical targets. A pi/2 Gouy phase shift through a one-axis focus compared to the more common pi phase shift of the two-axis focus is required to interpret the scattering results using a phy sical optics model.
