| Another example application for dual line scan inspection from two Imagers is when two sides of an object (web) must be inspected at the same time as depicted above. In this case, the web is not transparent and cannot be back lit to highlight defects. The defects may be surface defects that require low angle front lighting in order to highlight the textured defects. The defects may be two dimensional "spots" that require diffuse front lighting in order to reduce reflection and enhance the contrast between defect and surface. |
