Digital Holographic Interferometers Cameras for Remote Monitoring and Measurements of Mechanical Parts

Fast growing technology and requirements for testing of different types of materials and devices require new methods and systems for investigation of their parameters. Main interesting quantities are: shape, roughness, local materials constants and displacements of elements under load. One of many techniques for analysis of different types of elements is holography and holographic interferometry and in particular their digital versions. They allow remote monitoring and measurement of different parameters in the same setup. At the moment we observe fast development of holographic systems for microelements and microregion studies. Those systems with compact design and “black box” measurement approach should allow fast and accurate measurement performed directly at the element and often in outdoor environment.
