Abstract

The OMEGA project (Brite-EuRam 5470) intends to solve the problems arising from the lack of real time dimensional control on steel structural mill facility products. The main objective of the project is to assess the feasibility of an on-line, advanced passive non-contact measuring system, controlling complex geometry parts in adverse environment, featuring a high level of reliability and accuracy on measurements, with low cost. Such a measuring system will be based on Conoscopic Holography as the basic technology to be applied. Conoscopic Holography avoids some of the problems of conventional holography, such as the necessity of ultra high stability, coherent (but monochromatic) illumination and ultra high resolution sampling techniques. Thus, it is possible to produce holograms using incoherent light with a typical fringe period compatible with the resolution of normal electronic imaging devices, such as CCD cameras. In the application developed under this project the conoscopic head will have to meet requirements never tried before regarding the adverse working conditions. The paper will summarize the main objectives of the OMEGA project, now in progress, a description of the technology applied and the results available from the lab testing work when the paper is submitted.
