IMAGE DISPLAY DEVICE AND OBJECT APPARATUS |
| 摘要 |
An image display device includes a light source unit to emit light, an image forming element to form an image with the light emitted from the light source unit, a micro-lens array to be irradiated with the light forming the image, the micro-lens array including a plurality of lens columns arranged in a second direction, each lens column including micro-lenses being arranged in a first direction, the first direction and the second direction being perpendicular with each other, and a projection optical system to project light passing through the micro-lens array toward a transmitting and reflecting member. The condition B1<B2 and M1>M2 or B1>B2 and M1<M2 is satisfied. M1 denotes an average value of first-directional distances between optical centers of the two micro-lenses adjacent to each other in the first direction in the lens column group. M2 denotes an average value of adjacent intervals between adjacent axes, the adjacent axes each passing through a second-directional average position of the optical centers of the plurality of micro-lenses of each lens column in the lens column group and extending in the first direction. B1 denotes a first-directional magnification ratio of an optical system including the projection optical system and the transmitting and reflecting member. B2 denotes a second-directional magnification ratio of the optical system. |

1. An image display device comprising:
a light source unit to emit light; an image forming element to form an image with the light emitted from the light source unit; a micro-lens array to be irradiated with the light forming the image, the micro-lens array including a plurality of lens columns arranged in a second direction, each lens column including micro-lenses being arranged in a first direction, the first direction and the second direction being perpendicular with each other; and a projection optical system to project light passing through the micro-lens array toward a transmitting and reflecting member, wherein B1<B2 and M1>M2 or B1>B2 and M1<M2 is satisfied, in which M1 denotes an average value of first-directional distances between optical centers of the two micro-lenses adjacent to each other in the first direction in the lens column group, M2 denotes an average value of adjacent intervals between adjacent axes, the adjacent axes each passing through a second-directional average position of the optical centers of the plurality of micro-lenses of each lens column in the lens column group and extending in the first direction, B1 denotes a first-directional magnification ratio of an optical system including the projection optical system and the transmitting and reflecting member, and B2 denotes a second-directional magnification ratio of the optical system. |
