An　experimental　investigation　of　wave　propagation　coefficients　determination　of　the　granite　was　presented　in　the　present　study.　Firstly,　a　series　of　pendulum　impact　tests　were　performed　to　investigate　the　stress　wave　properties　of　the　granite.　High-speed　digital　image　correlation　(HDIC)　was　utilized　to　capture　the　displacement　and　velocity　at　the　free　end　of　the　impacted　granite　bar.　Subsequently,　the　HDIC-based　non-contact　method　was　introduced　for　the　determination　of　wave　propagation　coefficients　of　the　granite.　Finally,　experimental　studies　based　on　the　traditional　contact　method　using　strain　gauges　were　performed　to　validate　the　present　HDIC-based　non-contact　method.　The　results　show　that　both　the　attenuation　coefficient　and　wave　number　increase　as　frequency　increases.　Moreover,　the　propagation　coefficients　(attenuation　coefficient　and　wave　number)　determined　by　the　present　HDIC-based　non-contact　method　agree　well　with　that　determined　by　the　traditional　contact　method　using　strain　gauges.　The　present　HDIC-based　non-contact　method　can　be　used　to　predict　the　stress　wave　propagation　through　the　granite　effectively.
