Filed:

Aug 18, 1998

Appl. No.:

09/135734

Inventors:

Michael Hermann Wahl - San Diego CA

Phillip Gregory Roberts - San Diego CA

Assignee:

Veeco Tucson Inc. - Tucson AZ

International Classification:

G02B 704

US Classification:

2502013, 2505593

Abstract:

The present invention provides a method and apparatus for high-speed autofocus and tilt of an inspection surface in a microscope system. The method and apparatus herein described projects an array of spots, lines, circles, grids or other shapes on the surface to be adjusted. The superposition of the array on the surface is imaged by a CCD camera and captured for subsequent analysis. Analysis of the captured image determines both the distance and angle through which the surface must be adjusted to bring it into the focal plane of the optical system. Focus and tilt error is estimated by comparing image dilation and distortion with calibrated data.
