Abstract:

Non-contact contour measurements of helicopter rotor blades to accuracies of 0.0001 in. are possible via range finding by triangulation employing electro-optical techniques. A laboratory breadboard of such a system has been built and tested. The results of these tests indicate that the construction of a full prototype system is feasible and desirable. Author
