Abstract

There is an increasing demand for inspection equipment that is designed or adapted to meet individual problems. This paper describes some of the solutions proposed or effected by the Special Projects Team of an instrument manufacturing company. The examples chosen are: (1) A method of assessing the straightness of long tubes using a steel ball and an alignment telescope, giving an accuracy of 0.001 inch. (2) A versatile photo-electric device for determining the position of a light - dark boundary. (3) Measurement of the positions of holes entering a cylindrical bore, by means of a profile projector and special fixtures. (4) A coarse alignment system for civil engineering in which a spot of light from a laser source is projected at constant diameter over a wide range of distances. (5) Presentation of turbine blade profiles on a CCTV monitor, using a modified Schmaltz light-sectioning technique.
