A totally different method to the Matched Filter process, since no reference filter is required. Instead, the “Input” and “Reference” images are aligned and displayed alongside each other on the SLM. The two images are then Fourier Transformed together. A non-linearity (typically a camera or photodiode array) then captures the intensity distribution of transform, producing the Joint Power Spectrum (JPS). The JPS is then Fourier Transformed itself, producing an output of symmetrically identical pairs of correlation peaks, per match.
