Abstract
Abstract
Optical engineering uses research and development of laser technology, modern photonic detection/imaging systems and optical metrology for engineering applications. It has produced a wide range of processes and techniques from high-power laser material processing to high-sensitivity metrology and has applications in every industrial sector. Modern optical diagnostic techniques are providing new experimental and in situ data, which hitherto were considered to be unobtainable. Engineers are analysing these data in order to provide immediate design improvements in the performance of components. In addition, they use the data to refine theoretical/computer models of engineering processes, which in turn provide more accurate performance prediction. This paper introduces technology now available to the optical engineer and describes how it is being used to provide optical diagnostic techniques for both solid and fluid mechanics applications in industry. The gas industry has to deal with gas provision safely and efficiently from ‘drill bit to burner tip’ and has benefited significantly from optical engineering. Examples of optical diagnostic techniques and applications, which are used to improve this process, are described.
