A grating-lens combination unit is developed to form a scalingself-transform function that can self-image on scale. Then an arrayof many such grating-lens units is used for the optical interconnectionof a two-dimensional neural network, and experiments are carriedout. We find that our idea is feasible, the optical interconnectionsystem is simple, and optical adjustment is easy.
