Abstract
To a light converter including an optical effect element is applied an electric input having an amplitude exceeding the linear region of the characteristic of the light converter. The number of the peaks of the output reaching a maximum amplitude is added to the magnitude of a peak of the output not reaching the maximum amplitude thereby measuring the magnitude of the input. Two or more light converters with differential or cumulative inputs may be used.
