Abstract
Real-time image correlation is achieved by coupling coherent Fourier spectra inside saturable absorbers. Previously described optical correlators using nonlinear susceptibilities are strongly limited by the angular selectivity of Bragg diffraction in thick interaction cells. We overcame these difficulties by a special 3-D arrangement of the interfering beams. High-quality quasi-real-time holographic images, enabling cross-correlationof photographic transparencies free of detection noise, are demonstrated.
