An apparatus for determining the shape of a gemstone, including irregularities on its surface, is provided, The apparatus comprises a platform adapted to support the gemstone, a scanning system adapted to provide geometrical information concerning the three-dimensional convex envelope of the gemstone, an illumination system adapted to project on the gemstone a plurality of laser beams, an imaging system adapted to capture reflections of at least a part of said laser beams from the surface of the gemstone, and a processor. The processor is adapted to calculate, based on said geometrical information, a predicted reflection of each laser beam, to compare the captured reflections with said predicted reflections and to relate each captured reflection to its corresponding predicted reflection, to determine said shape of the gemstone based on the comparison and said geometrical information.

Apparatus for determining the shape of a gemstone

A method for automatically optically inspecting an electrical circuit (), comprising: acquiring at least one optical image of an electrical circuit (); generating at least one first inspection image from the at least one image and determining regions of candidate defects () therefrom; generating at least one additional inspection image for regions surrounding candidate defects (), said at least one additional inspection image at least partially including optical information not included in the at least one first inspection image; and determining whether the candidate defect () is a specious defect by inspecting the at least one additional inspection image.
