Abstract:
An image display apparatus includes a scanning optical unit configured to scan a laser light, a beam shaper configured to receive the laser light scanned by the scanning optical unit in a direction normal to a surface of the beam shaper, an illumination optical unit configured to transmit the laser light emitted from the beam shaper to a display panel, the illumination optical unit including an anamorphic lens and two reflective optical elements having free-form surfaces, the display panel configured to display an image based on the laser light transmitted by the illumination optical unit, and an eyepiece optical unit configured to concentrate an image light emitted from the display panel to an eye of an observer, the eyepiece optical unit including three reflective optical elements having free-form surfaces.
