Investigating performance of core materials by using holographic deformation measurement methods

Investigating performance of core materials is intended by using holographic deformation measurement methods in this study, two different applications of digital holography are used. Power losses occur in the core materials which are exposed to effect of magnetic field, is a changing structure depends on thickness and volume of core materials. In this study, amount of work due to deformation is done by core materials under effect of magnetic field, is computed. Knowing the amount of work done by core camples is important for detection of which sample has better core material characteristic. Two different techniques are used in this study. The holographic image of core sample which isn't applied deformation process is recorded by digital holographic interferometry method. Then, magnetic field applied to sample and new holographic image of sample under effect of magnetic field is recorded. It is identified phase difference between both holographic images. The amount of work done by core sample due to effect of magnetic field is computed by using phase difference which is obtained and improving different algorithms. The 4 different holographic images of core sample which isn't applied deformation process are recorded by phase shifting digital holographic interferometry method. Then, magnetic field applied to sample and new 4 holographic images of sample under effect of magnetic field are recorded. It is identified phase difference between both situation of sample. The amount of work done by core sample due to effect of magnetic field is computed by using phase difference which is obtained and improving different algorithms. After that the value of static magnetic field intesity is changed and previously procedures is applied again for this new condition. The results obtained both different methods are compared each other and proposed in this study.
