Abstract: A method and apparatus for combining multiple views of an object using a three-dimensional surface profiling apparatus, which compensates for depth of field effects, is described. The apparatus utilizes a single source and a single receiver to acquire the multiple views of small objects. A lens or a system of lenses adjust the focal plane to account for the shorter distance that the radiation will travel along a first optical path than along a second optical path, so that both images are in focus on the detector at substantially the same time. For large objects, a three-dimensional surface profiling apparatus utilizing more than one camera is used.

Abstract: The present invention provides a method and apparatus for reducing error in interferometric fringe stability and reproducibility in an interference fringe generator. In one aspect, the method for reducing error in interferometric fringe stability and reproducibility includes providing a light source, positioning a grating to receive light from the light source and positioning a projection lens having a focal length F to receive light from the grating. The projection lens projects the received light upon an object of interest positioned substantially at a distance d1 from the lens. Typically the lens is positioned substantially at a distance d2 from the grating. The values of d1, d2, and F are related by d2 being approximately equal to d1F/(d1-F).
