COBRA: New Interferometric Inspection Design Software

Coherent optical testing methods such as holography, electronic speckle pattern interferometry (ESPI) and shearography have proven capabilities for performing structural inspections. However, a recurring challenge for inspectors is the determination of the optimum inspection configuration and loading method. Typically inspectors rely on experience or trial and error methods. Often a single configuration is used for a variety of applications. This lack of inspection design can reduce inspection reliability for complex structures. Therefore, to provide an inspection design tool, we are developing a computer code which simulates inspection processes.
