Abstract
Provided are a series of analog quantities that are approximately proportional respectively to the components of a third array that is the product of a first array of components multiplied by a second array of components in a predetermined order. Light of intensity approximately proportional to the first component of the first array is directed to the input side of a modulator whose output light intensity is approximately proportional to an electrical signal applied to it. Applied to the modulator, while the light is passing through it, is a signal approximately proportional to the first component of the second array, so that the intensity of the output light from the modulator is approximately proportional to the product of the two first components. The output light from the modulator is directed to a detector for providing an electrical signal that is approximately proportional to the product of the two first components. After predetermined times, the above steps are repeated with the second then the third, etc., and finally with the last component of the first array and the last component of the second array to provide a similar electrical signal each time; and the individual product signals are directed to summers, so that each provides an output that is approximately proportional to a component of the third array.
