Multiplexed binary phase-only filters provide simultaneously multiple correlations for an input object. A theoretical harmonic analysis allows estimation of the crosstalk among component filters, caused by the nonlinear binarization. A method thresholding a combination of the component phase-only filters is proposed to recover the correlation peak intensities of the component filters. Experimental results using multiplexed binary phase-only circular harmonic filters for rotation invariant pattern recognition is presented.
