Abstract : The design of filters for optical pattern recognition is extensively studied for more than ten years. Indeed, optical correlation implementation leads to specific constraints in comparisons with classical signal processing technics. In particular, although the spatial matched filter is optimal for noise robustness, its limitations such as broad correlation peaks and low diffraction efficiency are well known. Many different approaches have improved some of these characteristics and a lot of work is still devoted to find trade-offs between them.
