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.

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.
