Abstract:

In this paper, we evaluated the advantages of using the Hilbert transform in an optical correlator. We reviewed state-of-art optical techniques that employ the Hilbert transform and, based on the principle of the classic Hilbert correlator, we performed simulations for this type of optical correlator. The simulation results confirm the efficiency of the Hilbert transform optical correlator for image recognition applications and certify the suitability of using this type of optical correlator in future applications, as a viable alternative to other techniques, either optical or digital.
