Abstract: A 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 processing subsystem has a channel formation capability for forming selected channels and developing channel output associated with each selected channel, with the channel output developed from collector output associated with at least one collection and detection module. Also, a spherical defect channel is described for detection of small spherical objects and defects with like geometries, using scattered light observed by the back collector output and P-polarized scattered light observed by wing collectors.

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. Certain of these components, most notably the beam source subsystem, the beam scanning subsystem and the optical collection and detection subsystem are modular for ready field replacement and/or maintenance. The optical collection and detection system features wing collectors in the front quartersphere and back collectors in the back quartersphere for collected light scattered from the surface of the workpiece. This can greatly improve the measurement capabilities of the system. Also included is a method for detecting asymmetric defects using the wing collectors and back collectors.

Abstract: A process for obtaining the periodic component in a data vector of data taken of a sensed property of an element driven by one or more rotary components (16b) over several rotations. The procedure comprises first forming the data vector asynchronously with respect to rotation of said one or more rotary components (16b). A series of marker signals representing the rotation of the one or more rotary components (16b) is also established. From these the periodic component of data in said data vector is determined as a function of the data in the data vector and the marker signals.

The optical collection and detection system features back collectors disposed in the back quartersphere, outside the incident plane, for collecting light scattered from the surface of the workpiece. The back collectors are disposed at a relative minimum in the portion of scattered light attributable to haze relative to the portion of scattered light attributable to defect scatter portion, or, alternatively, at a relative minimum in the Rayleigh scatter.
