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 visible-induced infrared luminescence images. Workflow for the capture of visible-induced infrared luminescence (VIL) images Equipment requirements: e Camera e LED light sources e UV/Visible-blocking filter (e.g. Schott RG830) 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 LED light sources and the camera as shown in Figure 2-34 and according to the recommendations in section b. Object Reflected Visible IR Luminescence mh d LED light source Visible-blocking filter (e.g. Schott RG830) 2) Place the UV/visible-blocking filter (e.g. Schott RG 830) in front of the camera. 3) If working in the studio, position the object following the recommendations referred to in section b.
