The project is realized as a part of INNOTECH Programme  on the program part In-Tech entitled: „Innovative opto-numeric system for plane displacement measurements and analysis of mechanical properties of materials and construction elements in diverse environmental conditions.”


The project has started on July 2014 for 48 months and is carried out by the consortium of 3 partners:

  • Astri Polska (leader)
  • Faculty of Mechatronics of Warsaw University of Technology
  • Institute of Aviation

The goal of the project is to develop an optical system for in-plane and out-of-plane displacement/strain measurements and for characterization of material properties. The system will compromise of two optical modules for non-invasive measurements and software for calculating material constants. This approach is called combined numerical-experimental model.

The system will allow:

  • anisotropic materials examination;
  • surface strain examination;
  • damage propagation examination;
  • static and fatigue examination;
  • examination of sample placed in environmental chamber
  • measurement of strain/displacement of engineering objects\


Astri Polska, apart from project leading, is responsible for:

  • defining project requirements (alongside with other members of consortium)
  •  designing of the OTEST system (alongside with other members of consortium)
  • modelling, designing and conducting numerical analysis of a miniaturized measurement system
  • OTEST system integration


Hardware aspects of the project will be based on:

  • Analysis and selection of optical field techniques for measuremen of quasi-flat surfaces
  • Modification of the selected techniques to enable their usage in designed measurement conditions
  • Development of the optical, opto-mechanical and electronic modules that are parts of OTEST system
  • Development of OTEST system software[/one_fifth]
  • Development of software responsible for processing and analysis of measurement data


OTEST system applications:

  • Non-destructive measurement methods enhanced by numerical analysis
  • Verification of the boundary conditions
  • Examination of local gradients of strain/displacement due to material non-homogeneity of the sample
  • Examination of cracks and defect propagation mechanics
  • Theoretical or numerical model assumptions verification
  • Examination of elements made of a particular material
  • Obtaining material constants of examined materials

Project co-financed by the European Regional Development Fund under the Operational Programme Innovative Economy
