ABSTRACT:
In an area of interest (AOI) display, a detailed image is projected on a screen at the area of interest while a background image is projected on the surrounding area such that the boarder between the two areas varies in an orbital oscillating pattern to accomplish visual blending. A combiner includes a transparent portion to accommodate projection of the background image at the area of interest. The opaque portion carries a mirror to reflect the detailed image filling the area of interest. The combiner is oscillated in an orbital pattern at a resonant frequency, e.g. 210 Hertz by a three phase electromechanical drive unit.
