  1. Non-Contact PhotothermalMultilayer Thickness Measurement Christian Florin (flo-ir) Andor Bariska, Dr. Nils Reinke, Prof. Dr. Beat Ruhstaller (ZHAW) www.flo-ir.chwww.icp.zhaw.chwww.idp.zhaw.ch

  2. Application (Samples only) www.flo-ir.chwww.icp.zhaw.chwww.idp.zhaw.ch

  3. Properties of Thickness Measurement Technologies www.flo-ir.chwww.icp.zhaw.chwww.idp.zhaw.ch

  4. Market Potential 1 = small 2 = medium 3 = big (Based on a marketing study from 2006/2007) www.flo-ir.chwww.icp.zhaw.chwww.idp.zhaw.ch

  5. Measuring Principle • Heating of a coating system (single or multilayer coating) with optical pulse • Non-contact measurement of IR radiation from the surface with high time resolution (<0.1ms) • Post-processing of the acquired data to determine coating thickness www.flo-ir.chwww.icp.zhaw.chwww.idp.zhaw.ch

  6. Development of an Idea to a CTI-Project • Experimentally detected dependency of IR-radiation from layer thickness (Christian Florin 2000 - 2003). • Price holder "Swiss Technology Award 2004" for • photothermal non-destructive measurements. • (Startup Label, 2004). • Verification of the photothermal effect to multilayer • coatings for thickness measurement (2006, • Arsenco AG). • CTI suggests academic partner ZHAW School of • Engineering for a follow-up project to develop • photothermal technology (2007). • The ICP Institute for Computational Physics and IDP • Institute for Data Analysis and Process Design joined • their complementary forces for this challenging • project. www.flo-ir.chwww.icp.zhaw.chwww.idp.zhaw.ch

  7. Industrial Project Partners • flo-ir • Specialized in consulting on IR measurements for non-destructive testing & evaluation and process control. • Experience goes back to 1984 • Swiss Technology Award 2004 • Five additional industry partners: • Thickness measurement and process control for coating and plastic foils production industry • Multilayer lacquering in automotive industry • Food packaging industry www.flo-ir.chwww.icp.zhaw.chwww.idp.zhaw.ch

  8. Academic Project Partners • ICP Institute of Computational Physics • Applies and develops numerical modeling software to solve multi-physics problems • Optics lab equipped for high-speed IR measurements • IDP Institute of Data Analysis and Process Design • Applies physical and statistical modeling to extract information from measurements • Develops data analysis methods • History of successful partnerships for R&D projects between institutes • Supported by School of Engineering mechanics workshop for prototype fabrication www.flo-ir.chwww.icp.zhaw.chwww.idp.zhaw.ch

  9. Example Result Ceramic Plate with multiple concrete coatings www.flo-ir.chwww.icp.zhaw.chwww.idp.zhaw.ch

  10. Project Successes • ZHAW produces first prototype: • Mobile, robust device (Laptop-controlled automation and data acquisition) • Software with newly developed model-based algorithms to determine layer thicknesses from measurements • Experience of flo-ir with project partners confirms wide applicability of measurement principle • Cooperation initiated by CTI continues beyond the project to develop this promising new technology www.flo-ir.chwww.icp.zhaw.chwww.idp.zhaw.ch

  11. Commercial Development Phase 1 Phase 2 Phase 3 m 1 2 3 4 5 6 7 8 9 10 11 12 • Introduction to the market: • Test measurements in the practice. (Phase 1) • Installation of basic equipment at key customers. (Phase 1 / Phase 2) • Training and conferences for non-contact thickness measurement.(Phase 1 / Phase 2) • Acquisition of technically competent sales partners. (Phase 2 / Phase 3) www.flo-ir.chwww.icp.zhaw.chwww.idp.zhaw.ch

  12. Continuing Cooperation • Measurement series with the prototype and lead customers • flo-ir will promote the measurement technique in the market • Further development of hardware and software at ZHAW • Possible new CTI project with focus on • modified prototype for specific application markets • extended analysis models • refined experimental techniques www.flo-ir.chwww.icp.zhaw.chwww.idp.zhaw.ch

  13. Conclusion We acknowledge financial support from CTI Check out our prototype at the CONTROL 2010 exhibition “SonderschauBerührungslose Messtechnik“ 5.-7. May 2010 in Stuttgart! www.flo-ir.chwww.icp.zhaw.chwww.idp.zhaw.ch
