  • Patent number: 5373362
    Abstract: A light source device for measuring shape.A laser beam emitted by a semiconductor laser is converged by a lens in a direction transverse to the laser junction. The laser beam emerging from the lens is diverged by a diverging means in the direction aligned with the laser junction, and passes through unchanged in the direction transverse to the laser junction.

  • Patent number: 4839525
    Abstract: A method of and an apparatus for measuring the coordinates of each edge of a tape is disclosed. The method comprises the steps of attaching a tape to a surface of an object, such as a three-dimensional subject, to be measured in such a manner that at least one edge of the tape is placed along a measurement line, such as an edge, on the surface, the tape and the surface differing from each other in reflectance; projecting a deflected spot beam onto the area of the surface of the object including the edges of the tape; and detecting the portion of the area the reflectance of which sharply varies, thereby calculating the two-dimensional coordinates of the thus-detected values. Accordingly, it is possible to accurately measure the three-dimensional configuration along the measurement line.
