We present an optical implementation of the Hamming net that can be used as an optimum image classifier or an associative memory. We introduce a modified Hamming net, in which the dynamic range requirement of the spatial light modulator can be relaxed and the number of iteration cycles in the second layer (or maxnet) can be reduced. Experimental demonstrations of the optical implementation of the Hamming net are also given.
