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： In an image display apparatus, between a reflection-type liquid crystal display panel and a light source for supplying illumination light thereto, a half mirror is disposed at an angle. In addition, in the optical path of the light reflected from the liquid crystal display panel and then reflected from the half mirror, a concave mirror is disposed, and, in the optical path of the light reflected from the concave mirror and then transmitted through the half mirror, a polarizing plate is disposed so that, out of the light reflected from the liquid crystal display panel, only the light that conveys an image is directed to an observer's eye. Alternatively, a polarization separation mirror is disposed in place of the half mirror, and a quarter-wave plate is disposed between the polarization separation mirror and the concave mirror instead of using the polarizing plate.

摘要： The light receiving or back-side surface (22) of an indium antimonide (InSb) photodetector device (10) substrate (12) is cleaned to remove all native oxides of indium and antimony therefrom. A passivation layer (26) is then formed on the surface (22) of a material such as silicon dioxide, silicon suboxide and/or silicon nitride which does not react with InSb to form a structure which would have carrier traps therein and cause flashing. The device (10) is capable of detecting radiation over a continuous spectral range including the infrared, visible and ultraviolet regions.

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.
