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. 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.

摘要： An optical collection system for use in a surface inspection system for inspecting a surface of a workpiece. The surface inspection system has an incident beam projected through a back quartersphere and toward a location on the surface of the workpiece to impinge on the surface. This forms a reflected beam that extends along a light channel axis in a front quartersphere, and forms scattered light having a haze scatter portion. The incident beam and the light channel axis form an incident plane. The optical collection system includes back collectors that are positioned in the back quartersphere for collecting the scattered light, where each of the back collectors is disposed in the back quartersphere outside the incident plane, and at a relative minimum in the Rayleigh scatter.
