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 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.

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 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： An I image display apparatus has a display portion that displays an optical image, a combiner that reflects light from said display portion to thereby enlarge an optical image represented by the light, and transmits light from an ambient object; and a display unit including a transparent plate-form holding member that holds said combiner. The image display apparatus is used with the combiner situated in front of a user's eye, and provides an enlargement of the optical image displayed by the display portion, so as to be superimposed on an optical image of the ambient object. And the transparent plate-form diopter adjusting member is provided that has an optical power and is attached to the display unit so as to be situated between the eye and the holding member.
