Performance of optical and hybrid joint transform correlators for tasks of optical security
Performance of optical and hybrid joint transform correlators (JTCs) for security verification of optical marks containing transformed phase masks (PMs) is studied. The peak-to-noise ratio (PNR) and relative intensity of correlation peaks are selected as basic criteria for comparative analysis of su...

The optically addressed spatial light modulator (OASLM) based on the chalcogenide glass photoconductor - nematic liquid crystal structure is considered. The experimental setup of an OASLM JTC is designed on the basis of this SLM. The relations a PNR and relative intensity versus an effective focal length of an optical Fourier processor are studied and the basic reasons limiting efficiency of the setup are analyzed.
