摘要： A deflecting unit deflects a plurality of light fluxes from a light source including a plurality of light emitting elements arranged in two-dimensional array. An coupling optical system between the light source and the deflecting unit includes an optical coupling element that collimates the light fluxes and a line-imaging element that images the light fluxes near the deflecting unit in a sub-scanning direction. A holding unit holds the line-imaging element in a state that a position of the line-imaging element is adjusted with respect to a direction parallel to the sub-scanning direction. A scanning optical system condenses the deflected light fluxes on the scanning surface.

摘要： A first optical system couples a light beam from a light source, including a first lens made of glass with a positive power and a second lens made of plastic with a negative power. A second optical system focuses the light beam from the first optical system onto a scanning surface and moves a light spot on the scanning surface in a main-scanning direction. One of an incidence plane and an output plane of the first lens is spherical while the other is spherical or flat. A cross-sectional plane of the second lens along one of the main-scanning direction and a sub-scanning direction has a non-arc shape on at least one of the incidence plane and the output plane.

摘要： An image display apparatus and a vehicle provided with the image display apparatus. The image display apparatus includes a light source unit to emit a laser beam, an optical deflector to deflect the laser beam two-dimensionally, and an intermediate image generator to perform two-dimensional scanning twice in a main scanning direction and a sub-scanning direction with the laser beam deflected by the optical deflector to generate an intermediate image of one frame, where the laser beam deflected by the optical deflector draws two scanning lines. In the image display apparatus, the two scanning lines have two different phases for the two-dimensional scanning for a first time and the two-dimensional scanning for a second time, respectively. In the image display apparatus, the two scanning lines have two different starting points for the two-dimensional scanning for a first time and the two-dimensional scanning for a second time, respectively.
