Topographical Identification

Scanning, digitizing, storing and retrieving topographical features on a mechanical component characterize the component for digital data processing.

Surface relief features of components, such as machine shafts, rifle bores, bullets, etc., uniquely identify the components and aid in assessing their quality. An automated data file may be constructed, manipulated and accessed once the identifying features of the components are digitized.

Referring to the figure, a light source, such as a laser 1, supplies a narrow light beam 2 to component 3. The beam 2 scans component 3 in direction 4 while component 3 rotates in direction 5 around axial support 6. Surface relief features on component 3 supply varying reflected light intensities to sensor digitizer 7. A processor 8 receives and stores data representing light intensities and surface positions. Operators access the processor via a terminal 9.

Unknown components may be uniquely identified by scanning their surfaces and comparing the digital representations of their surfaces with previously stored data. Component quality may be determined by comparing a component's surface features with previously stored accept able and unacceptable features.
