Spatially resolved HMSI images of the heart of the third pig model. (a) Multispectral $4\times 4$ VIS camera; (b) multispectral $5\times 5$ NIR camera; and (c) Multispectral $3\times 3$ VIS camera. One spectral band of the snapshot sensor data for (a) $\lambda =530\mathrm{nm}$, (b) $\lambda =746\mathrm{nm}$, and (c) $\lambda =515\mathrm{nm}$. (d) The intensity distribution of the TIVITA Tissue pushbroom camera image at $\lambda =750\mathrm{nm}$.
