  • System and method for signal processing for a workpiece surface inspection system
    Patent number: 7505125
    Abstract: 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 signal processing subsystem comprises a series of data acquisition nodes, each dedicated to a collection detection module and a plurality of data reduction nodes, made available on a peer to peer basis to each data acquisition nodes. Improved methods for detecting signal in the presence of noise are also provided.
    Type: Grant
