摘要：The process uses rollers to carry the paper (1) in a flat plane past two cameras(2,3) with associated light sources (4,5).The transport mechanism is designed with suitablewindows allowing optical aces to each face of the paper. The paper remains flat as itpasses across each camera. A third camera (6) and light source (7) measures light passingthrough the paper to determine its transparency.
