摘要： The light directed from a light source to a concave mirror and the light directed from a display device to an eyepiece optical system are intersected by each other in a layout. This allows the light source, the concave mirror, and the display device to be arranged in compactness adjacent to the eyepiece optical system without increasing the optical power of an illumination optical system. As the result, the apparatus can easily be minimized in the thickness or the overall size. A hologram optical element is provided where the relationship between the wavelength range Δλ1 at half of the diffraction efficiency of each of the three primary colors of the light in the hologram optical element and the wavelength range Δλ2 at half of the intensity of each of the three primary colors of the light emitted from the light source is defined by Δλ1

摘要： A volume-phase reflection hologram optical element is fabricated by exposing a hologram photosensitive material to two coherent light beams. One exposure light beam has an axis-asymmetric wavefront, and the other exposure light beam has focus points different in the optical axis direction (Z-direction) between on a plane (ZX-plane) including one of two directions (X- and Y-directions) mutually perpendicular on a sectional plane perpendicular to that light beam and on a plane (YZ-plane) including the other of those two directions. Thus, an image display apparatus is realized in which at the time of reproduction, the component of a predetermined wavelength of the image light diffraction-reflected by the hologram optical element is focused at positions different in the optical axis direction between on the ZX-plane and on the YZ-plane, offering different image viewing characteristics between in the X- and Y-directions.

摘要： A video image display device (1) is provided with an ocular optical system (12) that guides video image light from a display element (11) to the pupil of an observer through an ocular prism (21) and at the same time guides ambient light to the pupil of the observer through the ocular prism (21). The eyepiece optical system (12) has reflection planes set in the ocular prism (21) that are provided with three or more planes to fold down three or more times an optical path for the video image light from the display element (11), wherein an HOE (23) is formed on at least one plane of the reflection planes. The video image display device (1) satisfies a conditional equation that properly prescribes the relationship between an incident range of the video image light incident on the HOE (23) formed plane in the ocular prism (21) and a display screen size of the display element (11). Thus, the video image display device (1) can widely secure both a video image observation area and a see-through area with a small compact structure.

摘要： Variation of the wavelength of the light emitted from a light source is reduced by a wavelength variation reduction mechanism. Hence, wavelength deviation of the intensity peak of the light emitted from the light source from the diffraction-efficiency peak of a hologram optical element is reduced. Thus, even when a high-brightness light source is used, the light emitted therefrom can be diffracted with the hologram optical element efficiently. Moreover, the heat generated by the light source is efficiently rejected through the surface of a land portion of a flexible printed circuit, is then, via an insulating layer of the flexible printed circuit, efficiently absorbed through the surface of a heat absorbing member, and is then, via a shield conductor, led out of a casing, so as to be thereby expelled.

摘要： A video display device is provided with a light source, a display element, and an eyepiece optical system (14). The light source emits light which has at least one emission peak wavelength and has a wavelength width including one emission peak wavelength. The display element modulates the light emitted from the light source and displays video. The eye-piece optical system (14) comprises a volume phase reflective HOE (23) with diffracts and reflects video light from the display element and leads the light to a viewing pupil. An HOE surface (23a) is divided into a plurality of flat surfaces (31, 32, 33) disposed so as to be recessed on the viewing pupil side, and the plurality of flat surfaces (31, 32, 33) are continuous so as to have a common ridge line at a boundary between the flat surfaces adjoining to each other.

摘要： A hologram optical element is formed on a substrate so as to make an optical device. The hologram optical element is formed in an area smaller than an irradiation area of a beam for reproduction such as image light or object light on the substrate. Supposing that the beam for reproduction is made of a center beam having intensity higher than 50% of center intensity and other peripheral beam, the hologram optical element is formed on the substrate in a size for diffracting only the center beam so that a flare or a ghost can be relieved without using additional optical elements such as a shading plate.
