Modeling arrangement and method and system for modeling 3D surface topography

摘要

In one embodiment of the invention, a modeling arrangement for modeling a three-dimensional surface topography is disclosed. The arrangement images a surface modeled at a wavelength detected by the human eye along with a light source configured to generate substantially monochromatic and coherent electromagnetic radiation and the wavelength emitted by the light source. And a grating connected to the light source, the light source and the grating connected to the light source together to produce a diffraction pattern of a known shape on the surface to be modeled.
