OPTICAL SYSTEM OF DYNAMIC TRIANGULATION FOR MEASURING ANGLES AND COORDINATES IN A THREE-DIMENSIONAL SPACE.

摘要

The invention comprises an optical scanner system for measuring the angles and coordinates of an object in a three-dimensional space. The invention is characterized in that it comprises a coherent light positioner and a scanning opening, the coherent light positioning being dynamic and may be adjusted. In addition, the scanning opening intended to detect the reflection of the beam of the coherent light used for the optical scanning in the present invention, uses a cylindrical-shaped mirror in the scanning opening with a reflection surface at 45°. When the mirror of the scanning opening starts to spin at a predetermined speed and the reflection of the coherent light beam is projected at an angle C by the laser positioner, an electric pulse will be generated, which indicates the measurement of the angle B has started, the mirror keeps rotating and reflecting the light towards the photodetector, so that this sends an electronic pulse for indicating the end of the measurement. The angles B and C are useful for determining the angle ß. Triangulation is used for calculating the Cartesian coordinates of the reflection of the coherent light beam located in the interest point, therefore obtaining the three-dimensional information of the object.
