摘要： An illuminating device comprises a pair of light sources and a rod-like photoconductor. The rod-like photoconductor includes a pair of planes of incidence entered by the light from the light sources, a reflection surface having a plurality of prisms and an exit plane located opposite to the reflection surface. The width between the reflection surface and the exit plane at the planes of incidence of the rod-like photoconductor is smaller than the width of the light sources in the same direction. As a result, the brightness distribution of the light exiting from the rod-like photoconductor becomes uniform. The illuminating device is combined with a plate-like photoconductor to make up a planar illuminating device. Also, the illuminating device is combined with a liquid crystal panel to make up a liquid crystal display apparatus.

摘要： A high-resolution light-beam scanning apparatus utilizing only mass-producible holograms instead of utilizing auxiliary optical systems such as optical lenses or a mirror having curvature, and capable of compensating for disadvantages including scanning beam thickening and variation, failure of a rotatable hologram to rotate at a constant velocity, displacement of a scanning beam position in the scanning direction and the cross scanning direction due to a mode hop of a wavelength of a semiconductor laser, and deviation of a base of rotatable hologram from a parallel state. These disadvantages are detrimental to efforts for increasing the resolution of a hologram scanner and lowering the cost thereof. The light beam scanning apparatus includes at least two holograms with one being fixed and the other rotatable, where a rate of variation of a direction cosine of an object wave recorded on the fixed plate and taken in a scanning direction of the light on the scanning surface is configured to be different from a rate of variation of a direction cosine of the object wave recorded on the fixed plate and taken in a cross scanning direction of the light on the scanning surface, and focal distances of a light incident on said rotatable hologram are configured to be different in the scanning direction and in the cross scanning direction.

摘要： A position of an observer in a stereoscopic observing region is detected by a position detecting unit. A right-eye image and a left-eye image which are seen from the detecting position are formed by an image forming unit and displayed on a display. By setting an aperture position of a projection optical system, the right-eye image is projected to the right-eye position of the observer and the left-eye image is projected to the left-eye position, thereby allowing a stereoscopic image to be observed. Further, an aperture is set so as to project the right-eye image or left-eye image to a position different from the detecting position of the observer, thereby allowing a same image to be seen to both eyes of another observer and allowing a two-dimensional image to be observed.
