  • Illumination optical system and image display apparatus
    Patent number: 8810740
    Abstract: An illumination optical system includes a two-dimensional laser-array light source including a plurality of laser light sources arranged in a two-dimensional array on a plane; an integrator optical system configured to superpose incident light and emit the light to an irradiated surface; a plurality of first lenses disposed parallel to the plane and configured to superpose beams from the two-dimensional laser-array light source in a first axis direction and emit the beams to the integrator optical system while limiting a divergence angle in the first axis direction of the two-dimensional array; and a plurality of second lenses disposed rearward of the first lenses and configured to superpose the beams from the two-dimensional laser-array light source in a second axis direction orthogonal to the first axis direction and emit the beams to the integrator optical system while limiting a divergence angle in the second axis direction.
