Abstract

The design of an optical triangulation gauge based upon a linear CCD array operating with sub-pixel resolution is described . Experimental results are presented that demonstrate the basic performance characteristics of the system and its ability to perform rapid measurements on complex engineering objects with accuracies in the range 2 to 5 µm .
