d. Post-processing Photo-induced Luminescence Images
iii. Correction of UV-induced Visible Luminescence Images
The workflow for the correction of UV-induced visible luminescence (UVL) images is
designed to carry out correction for the factors affecting UV-induced visible luminescence
images, aS Summarised in Table 3-1 and discussed in Chapter 1, and using the data
collected as a result of the acquisition protocols outlined in Chapter 2. Figure 3-59 shows a
schematic of the workflow developed in the nip2 software indicating both the
transformations/corrections to be applied.
