Digital generation of phase-shifting fringes to provide an alternative to shearography
نویسندگان
چکیده
The aim of this work was to create digitally phase-shift images avoiding the mechanical adjustments of the PZT, testing them with the digital shearography method. It was tested using a well-known object, a cantilever beam of aluminium under deformation, and a tooth. The results presented the ability to create the deformation map and curves with reliability and sensitivity, reducing the cost, and improving the robustness.

In this paper a method for digitally recording four quarter-reference-wave-holograms (by CCD) in a Mach-Zehnder interferometer setup, and reconstructing the object wave-front by numerical method is presented. The terms of direct transmission, auto-correlation and conjugate wave in the four wave reconstruction are cancelled out and only one original object wave is left after overlapping. Reconst...
متن کاملDigital Shearography for Nondestructive Evaluation and Application in Automotive and Aerospace Industries
Digital shearograohy has demonstrated great potential in revealing defects in objects especially in detecting delaminations in composite materials. It is gaining more and more acceptance by automotive and aerospace industries in the field of nondestructive testing (NDT) of composite materials. A key optical component used in shearography is a shearing device in which the shearing amount, sheari...

In this paper, we report on the design and fabrication of a low-cost phase shifter for application in phase shifting interferometry. Phase shifting interferometry is a powerful method for surface characterization. It uses interference data recorded during a series of predetermined phase shifts to recover the induced phase by the object surface. These controlled phase shifts are typically perfor...

Distributed generation (DG) will play an important role in future power generation systems, especially in stand-alone applications. Three phase four-leg inverter is a well-known topology which can be used as an interface power converter for DGs. Thanks to the fourth leg to provide the neutral path, the four-leg inverter is able to supply balanced loads as well as unbalanced loads. In this paper...
متن کاملHigh precision deformation measurement by digital phase shifting holographic interferometry.
A digital phase shifting technique capable of quantitatively determining the phase of holographic interferometric displacement fringes is presented. This technique uses computer control to take data and calculate surface deformation. The phase value at each detector point can be calculated by taking four successive intensity data frames with the reference phase shifted between each frame. The d...
