Abstract
A new principal optical scheme for automatic recognition of the shape and relative position of inclusions in moving translucent objects is presented. A new criterion for automatic identification of structures (their localization) based on the analysis of the interference pattern projected on the surface of a CCD matrix, which is an element of the proposed scheme of an optical correlator based on the confocal laser tomograph, has been introduced. The results of this work may be of interest to the specialists in the field of non-destructive control; it can find application in the relevant fields.
