SCANNER WITH PHASE AND PITCH ADJUSTMENT |
摘要 |
A method for determining three-dimensional coordinates of an object point on a surface of an object, including steps of providing a transparent plate having a first region and a second region, the second region having a different wedge angle than the first region; splitting a first beam of light into a first light and a second light; sending the first light through the first region or the second region; combining the first light and the second light to produce a fringe pattern on the surface of the object, the pitch of the fringe pattern depending on the wedge angle through which the first light travels; imaging the object point onto an array point on a photosensitive array to obtain an electrical data value; determining the three-dimensional coordinates of the first object point based at least in part on the electrical data value.
