Abstract

This paper describes a system capable of measuring and storing the cylindrical coordinates describing the surface of a small object (< 10 mm). Two T.V. cameras are used to view an illuminated section of the surface and the z and r coordinates are extracted from the video signals and stored on floppy disc. The resolution of these coordinates is ≈ 32 μm. The θ coordinate is supplied by rotating the object so that a new section of the surface is analysed. The process is repeated until the whole surface has been covered.
