Abstract
We know that optical shadow-casting techniques (OST) may have wide use in optical computing. By using the shadow-casting setup as given in fig. 1, one can get all the 16 logic operations in the central box by (ABCD) of the output screen controlling the switching states of 4 LEDS marked by varies direct as, (beta) , (nu) , (delta) . But the only use of the central box (ABCD) in the output screen and at the same time the nonuse of the other boxes in that screen reflects a shift from the flavor of parallel processings. Here we want to show that the other blocks in the output screen can be successfully used to give us all the 16 logical and arithmetical operations in parallel by creating a proper LED pattern consisting of a minimum number of LEDs and accommodating the tristate number system properly.
