Figure 3 | B²-SRS deep tissue imaging of porcine brain.

Caption

Comparison of a, B2-SRS and b, C-SRS 3D images (Raman shift of 2935 cm-1) of porcine brain tissue. The pseudo-color scale represents the depth information. Both B2-SRS and C-SRS can generate comparable SRS signal levels at relatively shallower tissue regions (e.g., z<50 μm), while at deeper depths (e.g., z>100 μm), the SRS signal can only be distinctly visible in the B2-SRS image but is barely detectable in the C-SRS image.
