Objective
The goal of the BE-project "Interferometric Cineholography For Nondestructive Testing and Quantitative Inspection" is to develop a holographic interferometric inspection system which is capable of recording double-exposed holograms with a repetition rate of 25 frames per second, even under industrial environment conditions. Its purpose is to analyze non-sinusoidal, transient deformation and dynamic behaviour of test objects and material samples.
A holographic interferometric inspection system is being developed which is capable of recording double exposed holograms with a repitition rate of 25 frames per second, even under industrial environment conditions. Its purpose is to analyse nonsinusodial vibration, transient deformation and dynamic behaviour of test objects and material samples.
First results in recording holograms with the neodymium yttrium aluminium garnet (Nd: YAG) laser systems with 25 Hz have been achieved using silver halide film and the TV holographic recording device. With the TV system, the first computer based real-time image processing and evaluation results have been demonstrated.
The system uses two frequency-doubled Nd : YAG-lasers with sufficient coherence lenght and a pulse repetition rate of 25 Hz as a source for illumination. Three recording device alternatives, a siver halide camera and a thermoplastic camera, both including reconstruction units, and a TV-holographic camera, can be integrated. A real-time image analysis system is provided to evaluate the recorded holograms.
