发明名称 SYSTEM AND METHOD FOR INSPECTING A WORKPIECE SURFACE BY ANALYZING SCATTERED IN A FRONT QUARTERSPHERE REGION ABOVE THE WORKPIECE
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 optical collection and detection system features, in the front quartersphere, a light channel assembly for collecting light reflected from the surface of the workpiece, and a front collector and wing collectors for collecting light scattered from the surface, to, greatly improve the measurement capabilities of the system. The light channel assembly has a switchable edge exclusion mask and a reflected light detection system for improved detection of the reflected light.
