Vascular occlusion monitoring with the snapshot-hyperspectral-camera-based multispectral imaging system. (a) Finger dorsal skin blood absorption images at different time points of vascular occlusion under the outside pressure. (b) Real-time quantitative blood absorption response curves of fingers under the vascular occlusion and the contrast groups. (c) Finger dorsal $Sa{O}_2$ images at different time points of vascular occlusion under the outside pressure. (d) Real-time quantitative $Sa{O}_2$ response curves of fingers under the vascular occlusion and the contrast groups.
