Abstract
We solve the problems from the area of nondestructive testing (ND) of the material quality in our laboratory. It is very well known that an optical method (OM) called the holographic interferometry method (HIM) makes possible this check. This contribution deals with some results of research in detection of the carbon composite defects which were obtained by means of this OM. The searching of check processes is the main orientation of our research work. These processes make possible to evaluate the influence of the defects on the modification of the mechanical properties of the tested materials. Such results make possible to determine dangerous nature of these defects with respect to particular way of use of the inspected materials. At the same time the attention is given to the study of methods for searching of defects. In these cases appearances of some types of defects which are of frequent occurence are evaluated.
