Disclosed herein is an innovative micrometric measuring instrument which comprises a base, a flat entrainer, a microscope and a screen firmly engaged one another in a clustered construction instead of being constructed loosely and separately as that is usually seen in a conventional product. The structure includes a signal retrieval circuit formed within a disk located within a coaxial cable connector. Means are provided for preparing an emission surface of the target positioned in the standby position to have a predetermined morphology. An optical microsphere whispering gallery mode resonator is positioned to cover exposed core portion of each fiber and in contact with the conductive coating of each fiber. The result of processing the fuzzy rule may be converted to a crisp result and returned to the crisp rule engine. The switch includes two such modulators in a cross bar arrangement.
