ABSTRACT :

In this paper we demonstrate the feasibility of impact-induced transient deformations measurement by single-pulsed subtraction TV holography an the Fourier transform method with contouring fringes as spatial carrier. Fringe formation in single-pulsed subtraction TV holography and phase demodulation by the Fourier transform method are descried. Contouring fringes are proved to be well suited for introducing spatial carrier in the correlation fringe patterns. Experimental results are presented. Finally, the degree of immunity to environmental disturbances of this technique is discussed and improvements are proposed.
