    摘要: The laser picture formation device includes a two-dimensional modulation element performing video image modulation as well as four or more laser light sources having different center wavelengths. The video images which have no speckle noises at the wavelength region that has high visibility, which are realized by simultaneously emitting the laser lights of green (G) and yellowish green (Y) which have particularly high visibility, and video images which are vivid as cannot be represented by the conventional display, and which can be realized by controlling the laser lights of respective colors independently, can be displayed. Particularly, by modulating the two-dimensional modulation element and the laser light output with synchronized with each other, various video displays are enabled.

    摘要: A laser image display device includes: a first laser light source capable of outputting a laser light having a first wavelength; a second laser light source capable of outputting a laser light having a second wavelength; and a color output conversion controller capable of individually controlling power of the first and the second laser light source displaying the pixels constituting an image according to an input signal. When an input signal is contained at the end point of the color reproducible region and the laser light having the first wavelength is driven substantially by a first maximum power while the laser light having the second wavelength is driven substantially by a second minimum power, the color output conversion controller displays in pixels, a color contained in the color reproducible region excluding the end point in the pixels by using the laser light of the first wavelength at a first power below the first maximum power and the laser light of the second wavelength at a second power above the second minimum power.

    摘要: In a display unit which makes coherent light perform scanning on a screen to display an image, it is necessary to rotate a polygon mirror at ultrahigh speed for display of a high resolution image such as HDTV, and therefore, a high-performance polygon mirror must be employed, and further, noise and power consumption during rotation of the polygon mirror cause problems.Mirrors for multiple reflection (6a) and (6b) are inserted in a coherent light scanning optical system, whereby plural scanning lines can be obtained while one plane of the polygon mirror (5) scans one line of coherent light, leading to reduction in the rpm of the polygon mirror.

    摘要: In a semiconductor laser device (10) having different facet reflectivities, an electrode disposed on a stripe ridge (107a) is divided into four electrode parts (1), (2), (3), and (4), and a larger injection current is injected to an electrode part that is closer to a light emission facet side. Further, a carrier density distribution in an active layer that is opposed to the stripe ridge can be matched to a light intensity distribution in the active layer, thereby preventing degradation in high output characteristic due to destabilization of a transverse mode and reduction in gain which are caused by spatial hole burning.
