20080240502 | Depth mapping using projected patterns - Apparatus for mapping an object includes an illumination assembly, which includes a single transparency containing a fixed pattern of spots. A light source transilluminates the single transparency with optical radiation so as to project the pattern onto the object. An image capture assembly captures an image of the pattern that is projected onto the object using the single transparency. A processor processes the image captured by the image capture assembly so as to reconstruct a three-dimensional (3D) map of the object. | 10-02-2008 |
20100002950 | Methods and apparatus for wavefront manipulations and improved 3-D measurements - Methods and apparatus to perform wavefront analysis, including phase and amplitude information, and 3D measurements in optical systems, and in particular those based on analyzing the output of an intermediate plane, such as an image plane, of an optical system. Measurement of surface topography in the presence of thin film coatings, or of the individual layers of a multilayered structure is described. Multi-wavelength analysis in combination with phase and amplitude mapping is utilized. Methods of improving phase and surface topography measurements by wavefront propagation and refocusing, using virtual wavefront propagation based on solutions of Maxwell's equations are described. Reduction of coherence noise in optical imaging systems is achieved by such phase manipulation methods, or by methods utilizing a combination of wideband and coherent sources. The methods are applied to Integrated Circuit inspection, to improve overlay measurement techniques, by improving contrast or by 3-D imaging, in single shot imaging.
