Standard front lighting can cause inconsistent and low contrast of a target’s features due to shape, colour and surface finish.
Using a back light ensures transmission of the light through the target into the camera. If the target is opaque a silhouette is generated creating a strong contrast and outline for stable inspection.
Even if a target is transparent it may have a range of densities to it (such as layered material or liquid in a bottle). Contrast can still be achieved through the changes in the absorption and transmission of light in the target.
