Summary:A device for executing a scalar multiplication of vectors is constructed in the form of an interferometric adder for residue numbers. A plurality of series-connected, vector-component-controlled phase modulators are disposed in each of the phase-modulatable light beams existing for such adder. A phase modulator is provided for each component of a vector, and which generates a phase shift as a function of the components of the vectors to be multiplied which are supplied to it. This phase shift is proportional both to the component of the one as well as to the component of the other vector. The phase shift generated by each component amounts to 2 pi when the numerical value of the component is divisible by the corresponding module without remainder. The result of the scalar multiplication is derivable as a positionally notated number from the interference pattern or interference patterns produced after the radiation through the phase modulators.
