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. |

DETAILED DESCRIPTION I claim: 1.
A method for providing a series of analog quantities that are 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, comprising, directing light of intensity proportional to the first component of the first array to the light side of modulating means whose output light intensity is proportional to a known function of an electrical signal applied to it, applying to the modulating means, while the light is passing through it, a signal proportional to a function of the first component of the second array such that the intensity of the output light from the modulating means is proportional to a known function of the product of the two first components, then, after a predetermined time: directing light of intensity proportional to the second component of the first array to the input side of modulating means whose output light intensity is proportional to a known function of an electrical signal applied to it, applying to the modulating means, while the light is passing through it, a signal proportional to a function of the second component of the second array such that the intensity of the output light from the modulating means is proportional to a known function of the product of the two second components, and so on, in the same manner, and finally with the last component of the first array and the last component of the second array to provide an electrical signal that is proportional to a known function of the product of the two last components, and providing a series of output signals responsive to the sums of predetermined groups of output light intensities and proportional respectively to the components of the third array.
2.
A method as in claim 1, wherein the output signals providing step comprises providing an electrical signal proportional to a known function of the intensity of each output light, and combining additively the electrical signals for each predetermined group of output light intensities
