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 exposure amounts of R, G, and B laser light emitted from a fabrication light source are so adjusted that the diffraction efficiency at R, G, and B wavelengths in an optical element is commensurate with the light intensity at the R, G, and B wavelengths in the light emitted from a reproduction light source. For example, when the light intensity of the light emitted from the reproduction light source is increasingly low at the B, G, and R wavelengths in this order, the exposure amounts of the R, G, B, laser light emitted from the fabrication light source are so adjusted that the diffraction efficiency in the optical element is increasingly high at the B, G, and R wavelengths in this order. In this way, the hue of the light (reproduction light) obtained from the reproduction light source via the optical element can be adjusted to the hue desired with every reproduction light source used, while the most use is made of the light emitted from the reproduction light source actually used.
摘要翻译：从制造光源发射的R，G和B激光的曝光量被调整为使得光学元件中的R，G和B波长处的衍射效率与R，G和从再生光源发出的光的B波长。例如，当从再现光源发射的光的光强度依次为B，G和R波长越来越低时，从制造光发射的R，G，B激光的曝光量光源的衍射效率依次为B，G和R波长越来越高。以这种方式，通过光学元件从再现光源获得的光（再现光）的色调可以被调整到所使用的每个再现光源所期望的色调，而最多使用从再现发出的光光源实际使用。

摘要： When an optical device is produced by bonding on a transparent base member an optical element formed as a hologram, the optical element and the transparent base member are both formed of an acrylic material. In particular when, as an optical device, an eyepiece optical system is produced by holding an optical element between two transparent base members, the optical element, the transparent base members, and the adhesive with which the transparent base members are joined together are all formed of an acrylic material. In this way, by building an eyepiece optical system with a similar kind of material, namely an acrylic material, it is possible to obtain increased adhesion among the materials of the individual components of the eyepiece optical system without performing special processing. Moreover, the transparent base members formed of an acrylic material more securely absorb shock and external pressure than those formed of glass.
