摘要：
The present invention relates to double-diffraction optical correlators. According to the invention there is provided a multi-channel optical correlator for shape recognition wherein the lenses and the filters are all constituted by patterns of fringes ; each channel is fed from a quasi-monochromatic and quasi-punctiform light source, which may be spatially incoherent.
