In process control with optical coherence tomography


Production industry is facing increased challenges in delivering highest quality in short time at competitive prices.As the dimensions or crucial features of products and parts become smaller reaching down to the micrometerrange, the effort and connected costs to characterise and evaluate the product's properties accordingly areincreasing dramatically. Especially for the characterisation/inspection of complex geometries or critical featureslocated inside the materials, non destructive imaging technologies are of great advantage. Unfortunately,conventional available non destructive imaging and evaluation methods are either very costly and/or rather slow(e.g X-ray computer tomography) or they do not fulfil the requirements (like standard ultrasonics) for advancedapplications e.g. for high resolution inspection of microparts.This project aims to solve these problems by developing a novel, fast, compact, user-friendly, cost effective(affordable by SMEs) tomographic characterisation tool for industrial applications, based on optical coherencetomography (OCT). The OCT method has been originally developed for medical diagnostics and is intensivelypursued for medical purposes, but not for industrial applications with the effect that there are currently noindustrial OCT-scanners commercially available.In this project, a competent all European consortium, with 10 partners from 5 European countries, covering theset requirements for the development and application of OCT could be established. The consortium includesSMEs as technology providers, supported by the RTD performers, and SMEs as technology users who willdirectly test and evaluate the novel method to shorten process development times and to control their products inthe production process. An additionally established industry supporter group, and the technology user SMEs inthe project are already defining a future market for a fast and effective exploitation of the #'
