Paper Abstract

In this work, the results of the implementation of an optic correlator are presented. The optic correlator allows detecting, on the exit plane, the address of rotation of the objective. The correlation filter is the hologram of the self-image of the reference object, which is materialized in a BSO crystal. During the operation of the correlator, the exit plane exhibits harmonic space20. On the other hand, while the objective changes its angular position, the harmonic of order zero and the harmonic +1 or -1 exchange energy, as it is the address of rotation of the objective.
