    摘要: There is provided a display device in a viewfinder, including a diffraction grating whose shape is determined at an interface between first and second materials, at least one of the first and second materials being adapted to have a variable refractive index for light reflected by an object to be photographed, and control means for changing the refractive index of the first and/or second materials, wherein the control means causes the light from the object to substantially pass through the diffraction grating in a first state and causes the diffraction grating to partially diffract the light from the object to display a pattern in a second state.

    摘要: A DBR semiconductor laser is controlled in an image projecting apparatus, which includes the DBR laser having a phase and DBR region, a light wavelength converting device for converting fundamental-wave light emitted from the DBR laser into second harmonic wave light, an optical deflector for scanning the second harmonic wave in a one or two-dimensional manner, and a modulating portion for modulating the DBR laser. Coefficient calculating and wavelength adjusting steps are performed within a non-drawing time. The coefficient calculating step calculates at least one coefficient in a relationship between a DBR current to be injected into the DBR region and a phase current to be injected into the phase region for continuously shifting the wavelength of the fundamental-wave light. The wavelength adjusting step changes DBR current injected into the DBR region and phase current injected into the phase region based on the relationship.

    摘要: A surface optical device apparatus includes a surface optical device capable of emitting or receiving light through a surface thereof and a thick layer formed of a radiation-curable or electron-beam-curable material, such as a polymerizable resist. In the thick layer, a guide hole for inserting an end portion of a light-transmission member, such as an optical fiber, and a plastic optical fiber with a flat end face or a lens-shaped end face, therein is formed at a position corresponding to the surface of the surface optical device such that the surface optical device can be optically coupled to the light-transmission member inserted in the guide hole. The guide hole is formed in the thick layer by performing a patterning on the thick layer using photolithography to selectively harden the thick layer and developing the thick layer.
