The spatial field distribution of a quasi single-cycle THz pulse leads to a time-dependent lens-like refractive index profile in an electro-optic crystal, which changes the beam shape of a copropagating optical probe pulse. We used this effect to measure THz waveforms in a highly birefringent crystal.
