Patent ID: 7508513

Claim:
A measuring apparatus comprising, a first prism, said first prism having a first light-reflecting surface, a second light-reflecting surface, and a first optical guiding section between said first light-reflecting surface and said second light-reflecting surface, said first light-reflecting surface reflecting a first light ray reflected from a first location on a surface of an object to be measured to said second light-reflecting surface via said first optical guiding section, said second light-reflecting surface reflecting said first light ray reflected by said first light-reflecting surface, a second prism, said second prism having a third light-reflecting surface, a fourth light-reflecting surface, and a second optical guiding section between said third light-reflecting surface and said fourth light-reflecting surface, said third light-reflecting surface reflecting a second light ray reflected from a second location on said surface of said object to be measured to said fourth light-reflecting surface via said second optical guiding section, said fourth light-reflecting surface reflecting said second light ray reflected by said third light-reflecting surface, an optical lens which converges or diverges said first light ray reflected by said second light-reflecting surface and said second light ray reflected by said fourth light-reflecting surface, an image sensor which captures the light rays from said optical lens, and converts images of said first location and said second location into an electrical signal, and a display unit which displays on one screen the images of said first location and said second location based on said electrical signal.
