A system for generating an augmented reality image comprises a video camera for obtaining video data and a sensor for obtaining sensed data. In an exemplary embodiment, the control system, which can comprise a hardware control for setting-selection by a human operator, directs the regulating system to adjust the support assembly as needed. The sintered silicon nitride component includes high purity silicon nitride and a sintering aid consisting of silicon dioxide. Regions having object pixels are identified within the synthetic aperture image using an object identification, where the object identification utilizes one or more historically known target characteristics and one or more measured characteristic to obtain an output. An edge of the movable plate adjacent to and facing the facing surface of the second component is arranged to air ride on the facing surface of the second component. Also described are various articles such as protective films, optical displays, and windows, comprising such AR coating.
