Optical metrology in manufacturing automation

Abstract

Optical measurement sensors are increasingly available, often finding application in measurement and inspection of manufactured products. For example, theodolites and laser trackers are already used to calibrate jigs and tooling. Digital photogrammetry is used in dimensional inspection of assemblies such as aircraft wings. Such tasks demand high performance sensors with 2D and 3D capability, large working envelopes, high accuracy, low measurement latency and increased flexibility. The availability of sensors which meet and exceed such criteria is fuelling new possibilities in the manufacturing process itself. Fixed tooling may be eliminated and replaced by flexible fixturing under the control of embedded sensor systems. Sensor technology is reviewed and a novel application presented.
