摘要： An illumination light source includes a coherent light source in which a plurality of light emitting points that emit coherent light beams are arranged in a one-dimensional array; and a light magnifying unit that magnifies the coherent light beams that are emitted from the light emitting points so that a diameter of light emitted from the coherent light source in a direction perpendicular to a direction of arrangement of the light emitting points is larger than a diameter in the direction of arrangement of the light emitting points. The illumination light source also includes an optical fiber; and a light-converging optical system in which a magnification is set such that light emitted from the light magnifying unit is coupled to the optical fiber, based on a maximum diameter of the light emitted from the light magnifying unit.

摘要： An image displaying apparatus includes laser light sources corresponding to a plurality of colors, while at least one of the laser light sources corresponding to one of the colors includes a plurality of wavelength conversion laser light sources corresponding to a mutually same color and has a plurality of outputs. The image displaying apparatus is operable to display a color image by causing a spatial modulation element to perform a spatial modulation process on laser beams output from the laser light sources by using a field sequential method. When the spatial modulation element performs the spatial modulation process on the laser beams output from one of the laser light sources (e.g., the green laser light source) having a plurality of outputs, a drive controlling device causes green laser emitting units serving as the wavelength conversion laser light sources to sequentially output pulses so that the laser beams output from the green laser emitting units continuously form substantially constant laser outputs that have substantially the same peak power as each other.

摘要： Plural collimator lenses are arranged corresponding to plural laser light sources to collimate light beams emitted from the laser light sources into substantially parallel light beams, respectively. A condenser lens focuses the substantially parallel light beams. A coupling optical element, on which light beams focused by the condenser lens are incident, couples the light beams into a single light beam. The laser light sources are arranged such that a longitudinal direction of an emitting region of each of the laser light sources is coincident with a radial direction of the condenser lens.

摘要： A light diffusion element includes a light diffusion layer that contains at least two types of liquid crystal molecules each having a different light scattering characteristic defined by a voltage and a refractive index. A pair of electrodes sandwiches the light diffusion layer, an applying unit generates and applies a variable voltage to the pair of electrodes, and a voltage changing unit varies the voltage generated by the applying unit. The voltage changing unit varies the voltage such that each of the refractive indexes of the liquid crystal molecules in the light diffusion layer changes temporally.
