An AWG is provided which realizes high wavelength isolation at low cost. The subsystems are built and modeled as services, and their management, specifically their failure recovery, is done in a manner similar to that of services and resources managed by the management system. Movable electrodes are extended outward from both sides of the mass to a predetermined length. The resolver rotor is attached to the shaft on an opposite side of a drive rotor relative to the bearing. Brightness control is simulated by attenuation filters that fit over the objective lens.
