 note = {We propose a scheme for frequency-resolved single-shot spectroscopy with an echelon mirror.The echelon mirror is employed to generate spatially encoded time delays for the white-lightcontinuum probe beam; it produces a temporal step of 66 fs and an overall time delay of 33 ps.We demonstrate broadband pump―probe imaging spectroscopy and present time―frequency two-dimensional images of the transient absorption of β-carotene between 420 and 630 nmwith single-shot detection. The results show that this technique is a powerful tool forobserving the ultrafast, broadband transient dynamics of materials that exhibit irreversiblereactions or deterioration by laser pulse irradiation.},
