Images of the mathematically reconstructed ambient stray radiation are also available in this column of the “results” tab (see later). Correcting for the “pigment-binder’” interaction (Kubelka-Munk) 30) Click on the “vilkm” tab (Figure 3-91). Column J] uses the corrected VIS, IRR and VIL images (automatically carried over from the “viscalib”, “specden” and “vilstray” tabs, respectively) to calculate y, a function which expresses the extent to which the pigment particles absorb the light emitted by the luminescent materials (for more details see Chapter 1).
