From: Orientational Mapping Augmented Sub-Wavelength Hyper-Spectral Imaging of Silk
High resolution 1.9 μm ATR maps of transverse (T) cross sections of silk (Bombyx mori) with laser 515 nm/230 fs irradiated spots; laser pulse energies, E p = 85 nJ (a) 170 nJ (b) on the sample; the polarisation was linear. The lateral step size was 0.5 μm; as-measured pixelated absorbance maps are presented. Polarisation of incident light onto ATR prism was s (in the plane of image; along y-axis).
