Single-shot dual-scale photoacoustic microscopy enables ultra-sparse sampling reconstruction of optical-resolution imaging

Optical-resolution photoacoustic microscopy (OR-PAM) enables label-free, subcellular-resolution microvascular imaging, but the speed-resolution trade-off remains a bottleneck. While sparse sampling accelerates acquisition, the disparity between OR-PAM’s tight optical focus and enlarged scanning steps causes irreversibl...
