| abstract | Describe a kind of equipment for being used to watch the image of jewel.The equipment includes being used for gemstone support is being observed into the supporting construction of position.Include guiding observation position into according to light structures illuminating multiple directional light sources of jewel.Supporting construction and light structures can rotate relative to one another around rotation axis.Imaging device is set to obtain the image of the jewel in observation position at multiple relatively rotation places between light structures and supporting construction；The imaging device has the imaging axis through observation position.Supporting construction is provided so that can be from jewel be placed in the way of in the range of the inclined inclination angle of rotation axis by the normal of the selected facet of jewel at position.Directional light sources are configured so that for any inclination angle in the scope at least one in the directional light sources will be reflected specular into the imaging device at least one rotation position of supporting construction from selected facet. |
