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： 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： An image display apparatus has: a display element for displaying an image; a light source section for supplying an illumination light to the display element; a reflection type hologram for diffracting and reflecting the illumination light so as to guide the illumination light to the display element; and an eyepiece optical system for guiding an image light from the display element to an eye of a viewer so as to provide an enlarged virtual image of the image. The reflection type hologram has diffusing properties. Since the reflection type hologram diffuses the illumination light, an incident angle of the illumination light with respect to the display element is widened to a certain extent. Since the display element does not change a propagating direction of a light ray, a propagating direction of the image light is widened similarly to widening of the incident angle, thereby enlarging the observation pupil.
摘要翻译：图像显示装置具有：显示图像的显示元件; 用于向显示元件提供照明光的光源部; 用于衍射和反射照明光以将照明光引导到显示元件的反射型全息图; 以及用于将来自显示元件的图像光引导到观看者的眼睛的目镜光学系统，以便提供图像的放大的虚像。反射型全息图具有扩散性。由于反射型全息图漫射照明光，照明光相对于显示元件的入射角度被扩大到一定程度。由于显示元件不改变光线的传播方向，所以与入射角度的加宽类似，图像光的传播方向变宽，从而扩大观察光瞳。
