Abstract A shock-accelerated flying foil is diagnosed with a chirped pulse spectral interferometry. The shock is pumped by a 1.2 ps chirped laser pulse with a power of ～ 1014W/cm2 at 785 nm irradiating on a 500 nm aluminum film and detected by a probe pulse split from the pump based on a Michelson spectral interferometry. A flying foil of ～ 5.595 x 10-6g in ～ 400μm diameter was accelerated to ～ 165 nm away from the initial target rear surface at ～ 1.83km/s before ablation.
