发明名称 SYSTEM AND METHOD FOR CONTROLLING LIGHT SCATTERED FROM A WORKPIECE SURFACE IN A SURFACE INSPECTION SYSTEM
摘要 A surface inspection system, as well as related components and methods, are provided. The surface inspection system includes a beam source subsystem, a beam scanning subsystem, a workpiece movement subsystem, an optical collection and detection subsystem, and a processing subsystem. The system features masking positioned in the collection and detection subsystem arranged to selectively prevent a portion of scattered light from passing through. Also included is a scatter absorbing system having a series of scatter absorbing elements for minimizing unrelated to the scatter associated with a desired location on the surface.
