Some application aspects of digital holography

School of Electrical Engineering, J.J. Strossmayer University in Osijek, Croatia

This talk presents some basics of digital holography processes. The aspect of digital holography application in pattern defect detection is described. Digital holography is used to amplify small discrepancies (difference) in images of the same size in pixels. This method is applied on ceramic tiles industry to alleviate pattern defect detection. Next aspect of digital holography application in coding processes is described. The information represented in form of a one-dimensional finite length field is transformed in hologram and its reconstructs are analyzed. The described methods use intensive mathematical calculations and parallel algorithms are recommended for their calculations. The basic trade-off is analyzed.
