8) Image of uniform reflective board under experimental conditions for flat fielding the UVreflected image. A workflow has been developed to ensure thatthese reguirements are collected according to the optimised and standardised acquisition protocols. The instructions below describe the workflow for the capture of UV-induced visible luminescence images. Workflow for the capture of UV-induced visible luminescence (UVL) images Equipment requirements: e Camera e UV radiation sources e UV safety glasses e UV-blocking filter (e.g. Schott KV418 +IDAS-UIBAR) e Macbeth colour chart (not required but remains in the shot from previous image for continuity/image registration) e Spectralon diffuse reflectance grey scale or any number of Spectralon diffuse reflectance standards as available. Set-up 1) Position the UV radiation sources and the camera as shown in Figure 2-31 and according to the recommendations in section b.
