Abstract

In order to achieve the above object, an image display apparatus according to an embodiment of the present technology includes a light source section and one or more optical components. The one or more optical components include an optical surface for dividing the light emitted from the light source into a plurality of light beams to be converged and a reflective surface for reflecting the plurality of light beams converged by the optical surface, and emit the plurality of light beams reflected by the reflective surface from the optical surface.

Claims (37)

1. An image display apparatus, comprising:

a light source section;

a concave mirror that reflects light emitted from the light source section towards one or more optical components, wherein the concave mirror is disposed between a first condenser lens and a second condenser lens; and

the one or more optical components, including:

an optical surface that divides the light emitted from the light source section into a plurality of light beams; and

a reflective surface for reflecting the plurality of light beams converged by the optical surface and emitting the plurality of light beams reflected by the reflective surface from the optical surface, wherein the one or more optical components include a first optical component and a second optical component, and

a beam splitter that splits the light emitted from the light source section to each of the first optical component and the second optical component, and combines the plurality of light beams reflected from each of the first optical component and the second optical component.

2. The image display apparatus according to claim 1 ,

wherein the optical surface is configured of a plurality of lenses arranged two-dimensionally, and

wherein the reflective surface reflects the plurality of light beams converged by each of the plurality of lenses toward a lens surface of each of the plurality of lenses.

3. The image display apparatus according to claim 2 ,

wherein the reflective surface is arranged so as to position a focal plane of each of the plurality of lenses in a vicinity of each surface of the plurality of lenses.

4. The image display apparatus according to claim 1 ,

wherein the optical surface and the reflective surface are arranged to face each other.

5. The image display apparatus according to claim 1 ,

wherein the optical surface and the reflective surface are integrally formed.

6. The image display apparatus according to claim 1 , further comprising:

a collimating optical system for converting the light emitted from the light source section into collimated light and guiding the collimated light into the optical surface.

7. The image display apparatus according to claim 1 , further comprising:

an image display element; and

an illumination optical system that guides the plurality of light beams reflected from the one or more optical components to an image display surface of the image display element.

8. The image display apparatus according to claim 7 ,

wherein the illumination optical system superimposes the plurality of light beams reflected from the one or more optical components on the image display surface.

9. The image display apparatus according to claim 1 ,

wherein the reflective surface has a plurality of reflective areas that reflect each of the plurality of light beams.

10. The image display apparatus according to claim 9 ,

wherein each of the plurality of reflective areas has a same shape.

11. The image display apparatus according to claim 9 ,

wherein each of the plurality of reflective areas has a planar shape.

12. The image display apparatus according to claim 9 ,

wherein the light source section has a plurality of light sources arranged at different positions from each other, and

wherein each of the plurality of reflective areas has a shape corresponding to a positional relationship of the plurality of light sources.

13. The image display apparatus according to claim 12 ,

wherein each of the plurality of reflective areas has a planar portion in a planar shape formed in a center of each of the plurality of reflective areas, and a tapered surface portion extending obliquely from the center of each of the plurality of reflective areas to a peripheral edge.

14. The image display apparatus according to claim 1 ,

wherein the light source section has a plurality of light sources arranged at different positions from each other, and

wherein the one or more optical components are arranged so as to have different angles from each other corresponding to positions of the plurality of light sources and have a plurality of reflective surfaces, each of which reflects light emitted from a corresponding light source of the plurality of light sources.
