Abstract

An improvement for holographic nondestructive testing in the field of information processing is proposed. It makes use of an optically generated zone plate for obtaining an interferometric hologram of an object suffering a deformation. This allows quick data acquisition and can be used outside laboratory conditions. Experimental results are discussed, and a brief mathematical analysis from the point of view of Fourier optics is also given.
