摘要： Disclosed is a diffractive optical element which includes a diffractive grating pattern ion a base plate. The diffractive grating pattern includes a plurality of phase gratings arranged in parallel lines extending along a predetermined direction to cause diffraction of an incident beam. Each of the plurality of phase gratings has an asymmetrical phase pattern. There is a phase gap, &Dgr;P, representing a phase difference (in radians) between an end point and a beginning point of each phase pattern. The phase gap, &Dgr;P, is substantially equal for each of the plurality of phase gratings and satisfies the relationship. 0.7&pgr;

摘要： Disclosed is a multi-beam optical system that includes a laser source, a diffractive beam dividing element that divides the light beam emitted from the laser source into a plurality of light beams, a propagation optical system through which the divided light beams propagate, a polygon mirror and a scan lens. The propagation optical system includes a curved surface mirror that is arranged such that center axes of the reflected light beams are spatially separated from center axes of the incident light beams at a predetermined separation angle. The diffractive beam-dividing element Is arranged such that the center axis of the incident light beam is inclined with respect to the normal to a diffraction grating surface thereof so as to compensate bending of a beam spot line, along which the beam spots align, depending on the separation angle of the curved surface mirror.

摘要： A beam splitting element includes a transparent substrate and a diffractive grating formed on the substrate for dividing an incident beam into a plurality of diffracted beams. The diffractive grating has a plurality of identically formed belt-shaped phase patterns that are arranged in parallel lines at equal pitches. The phase pattern has a sectional shape in a plane perpendicular to the parallel lines that causes non-linear phase difference to the beam passing therethrough within one pitch. Further, the adjacent phase patterns are connected without phase gaps at the boundaries therebetween.

摘要： A polarization converter having a planar light guide element is disclosed, in which at least one of front and rear surfaces thereof defines a light emission surface and one edge surface defines an initial edge surface for unpolarized light, and at least one corrugated reflection boundary surface being provided in the light guide element. The reflection boundary surface is defined by at least two adjacent optical media having different refractive indexes. The normal vectors of each surface are within a normal surface, so that light incident upon the initial edge surface can be emitted from the light emission surface. A lighting device for an LCD panel using a polarization converter is also disclosed.

The deflecting system includes an erecting system positioned between the objective lens and the eyepiece lens. The finder system also includes an LCD panel that is located on an image plane of the objective lens with the LCD panel displaying information which is viewed through the eyepiece lens. A first polarizer is positioned between the objective lens and the LCD panel while a second polarizer is positioned between the LCD panel and the eyepiece lens. The first and second polarizers are arranged such that their transmission axes are perpendicular to each other.
