An erecting equal-magnification lens array plate includes: first and second lens array plates; first, second and intermediate light shielding member. The first, second and intermediate light shielding member are halved by a splitting plane parallel with the main scanning direction. One of the first light shielding member pieces, one of the second light shielding member pieces, and one of the intermediate light shielding member pieces produced by halving the members are integrated to form a first holder piece. The other of the first light shielding member pieces, the other of the second light shielding member pieces, and the other of the intermediate light shielding member pieces produced by halving the members are integrated to form a second holder piece. The erecting equal-magnification lens array plate is assembled by sandwiching the first lens array plate and the second lens array plate by the first holder piece and the second holder piece.

An in-vehicle stereoimage display apparatus includes a display device, an erecting unit magnification lens module spaced from and facing toward a display screen of the display device for forming an erecting unit magnification stereoimage of an image displayed on the display screen, a lens movement mechanism for movably supporting the erecting unit magnification lens module, and a controller for changing the position of the erecting unit magnification lens module in accordance with the travel velocity of a vehicle. In one example, the controller increases the distance between the vehicle driver's eyes and the erecting unit magnification stereoimage as the travel velocity of the vehicle increases.

An imaging optical system a high quality image may be implemented by determining the optimum design conditions for suppressing the generation of ghost while holding uniform and sufficient light using a simulation method. In the imaging optical system having a slit, the requirements for removing the stray light are the inclination of a lens arrangement direction, the slit width, the lens pitch, the view angle, and the height of the light-shielding wall. The slit location, the lens thickness, and the lens row width do not affect the stray light removal, but affect the brightness. In the imaging optical system having no slit, the essential requirements for removing the stray light are the height of the light-shielding wall and the lens pitch. The lens thickness and the lens row width do not affect the stray light removal, but affect the brightness.

A stereoimage formation apparatus includes two lens array plates, each of which includes microlenses having optical axes and peaks. The optical axes of the microlenses are parallel to one another. The optical axes of the microlenses in one of the lens array plates are aligned with the optical axes of the microlenses in the other lens array plate. The peaks of the microlenses in one of the lens array plates come in contact with or are located proximal to the peaks of the microlenses in the other lens array plate. The microlenses of each lens array plate each have a predetermined spherical aberration greater than a predetermined minimum spherical aberration.

摘要:
Spherical convex micro-lenses are arranged between rectangular grooves adjacent to each other of a lens plate. The arrangement of convex micro-lenses is made to be in parallel with the short-side direction of the lens plate, namely, the direction of the rectangular grooves. Since stray light appears mainly on the convex micro-lenses arranged in the long-side direction of the lens plate, the stray light to appear in the long-side direction of the lens plate is removed by forming grooves at regular intervals in the long-side direction of the lens plate and forming a light absorbing film in each of the rectangular grooves. Or the stray light to appear in the long-side direction of the lens plate is removed by making the direction of arrangement of convex micro-lenses different from the long-side direction of the lens plate.
