Describe 3-D laser scanning.
What will be an ideal response?
Laser scanning systems use a laser projector and cameras to determine part dimensional coordinates to a high degree of accuracy. During a scan, the projector shines a series of white-light stripes on the object. The two cameras pick up the light and use the principle of triangulation to determine the point's x-, y-, and z-coordinates. As many as 1.3 million coordinate points can be obtained in one scan session in less than 24 hours with an accuracy of 0.025 mm per point. Similar to working with a CMM system, the points can then be downloaded to a CAD system for solid modeling creation. However, due to the high cost of both CMM and laser scanning systems, you will likely be using rulers, scales, and calipers for any mechanical dissection projects you are involved in at the university.
