    Abstract: Method and apparatus are provided for automated determination and adjustment of height and tilt of a substrate surface within a lithography system. The method includes: directing a beam of light onto the substrate surface, which reflects off the substrate surface as a reflected beam; optically splitting the reflected beam into a first reflected beam portion and a second reflected beam portion; impinging the first reflected beam portion onto a first detector plane of a first optical detector to generate intensity data, and impinging the second reflected beam portion onto a second detector plane of a second optical detector to generate intensity data, and utilizing the generated data in determining height and tilt of the substrate surface relative to a nominal writing plane of the lithography system. Responsive to the determination, focus or tilt of the system's writing beam, or position of the substrate surface within the system, is adjusted.

    Abstract: Virtually augmented endoscopy includes overlaying optical endoscopy image data with a virtual endoscopy model. Image distortion in the optical endoscopy image data can be substantially reduced. Features in the virtual endoscopy model can be correlated with features in the optical endoscopy image data to improve examination performance. A correlation path through the virtual endoscopy model can be determined that reasonably follows the physical path of an endoscope. A 2D or 3D correlation model can be generated from the image data and correlated to the virtual endoscopy model. Correlation between the scan data domain and the image data domain can use either the correlation path, correlation model or a combination thereof. CAD tools and other features of virtual endoscopy can then be applied to enhance the performance of optical endoscopy.
