Sažetak
This paper presents a method for detecting the small changes in image patterns applied on ceramic tiles using differential digital holography. Holograms are constructed from tile images using composition of spherical waves. One hologram is created from ceramic tile with correct pattern and the other hologram is created from tile with small error in pattern. The two holograms are subtracted and resulting hologram is observed. Next step in the process is creating image from subtracted holograms. The results show that for small change in the tile pattern there is a great alteration in the hologram and reconstructed image. The experiment is repeated with different tile errors in patterns.
