摘要： An image display apparatus has a display section for displaying an image, an eyepiece optical system, and a transparent plate-shaped member for holding the eyepiece optical system. The image display apparatus is used with the eyepiece optical system placed in front of a viewer's eyes and with the plate-shaped member facing the eyes. The image display apparatus directs light from the display section through the eyepiece optical system to the eyes so that the viewer is presented with a virtual image of the image displayed on the display section and simultaneously permits light from the outside world to be transmitted through the plate-shaped member so as to be directed to the eyes so that the viewer is presented with an image of the outside world. The boundary surface between the eyepiece optical system and the plate-shaped member is so arranged as not to reflect light from the outside world incident thereon at angles of incidence greater than the Brewster angle toward the eyes.

摘要： An optical device having a dioptric correction device comprises a reference image display unit which is placed in the optical path extending from an object image to the optical system. The reference image is used for dioptric correction. The left and right reference images are different and are displayed on the left and right reference image display units when dioptric correction is performed. The reference image display unit is placed at a predetermined position between the optical system and an image display unit. Since the reference image is positioned at the predetermined position, both of the image of the image display unit and the reference image may be seen clearly.

摘要： A resonant optical device has a rod-like resonator made of a fiber-reinforced resin for resonant vibration. A reflecting mirror is supported on the leading edge of the resonator. A drive unit oscillates the resonator in a circumferential direction. The base edge of the resonator is anchored to a stationary platform. The reflecting mirror is oscillated by a torsional oscillation produced by oscillation from the drive unit so as to scan light incident on the reflecting mirror. The resonator satisfies the expression G/.rho..gtoreq.12.times.10.sup.6 Pa.multidot.kg.sup.-1 .multidot.m.sup.3, where the horizontal elastic modulus of the resonator is designated G, and the density is designated .rho.. The resonator also satisfies the expression .tau./G.gtoreq.0.01, where the torsional stress tolerance is designated .tau.. In one embodiment, the fiber-reinforced resin is a carbon fiber-reinforced resin.

摘要： At least one of right and left image display apparatuses is provided with an optical axis adjustment mechanism. The optical axis adjustment mechanism changes relative positional relationship between an image displayed on a display device and an ocular optical system in a direction intersecting an optical axis to thereby adjust an angle formed by a pair of right and left optical axes. In this condition, a light source is so arranged as to be substantially conjugate with an optical pupil. The optical axis adjustment mechanism changes the positional relationship described above without changing a position of the optical pupil relative to the ocular optical system. This permits, even when the apparatus is originally designed such that light intensity is high at a designed optical pupil position, achieving the light intensity at this optical pupil position even after optical axis adjustment. Moreover, since the position of the optical pupil relative to the ocular optical system is not changed through the optical axis adjustment, image light can be guided to the optical pupil by utilizing a portion of the ocular optically system designed so as to suppress occurrence of aberration.

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： 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
