摘要： A miniature visual display has an optical lens system with at least two separated lens elements positioned to admit a scanning mirror between them. The scanning mirror is driven with an oscillatory motion causing an image of a light source which is reflected in the mirror to appear to sweep across the field of view of an observer looking into the system. The light source is typically a linear array of light-emitting diodes, and the diodes are controlled to emit light flashes in synchronism with the scanning mirror oscillation frequency to generate a virtual raster image. The two lens elements are selected and arranged so that the magnification power of the system is split between the lenses. A viewer looking into the system sees a virtual image apparently positioned at a comfortable viewing distance which is in uniform focus over the entire viewing area.
