SIR-PAM imaging of zebrafish embryos in vivo. a, b Depth-encoded whole-body images of a zebrafish larva obtained by SIR-PAM a and conventional PAM b. The focal plane is located at z = 0.0 mm. c−e Normalized PA amplitude profiles along the dashed lines. Finer structures can be resolved by SIR-PAM due to its improved lateral resolution within a large RIAR. Scale bars, 200 µm
