Color image generation systems are disclosed for the reproduction of real or virtual, two-dimenional or three-dimensional, color, or monochrome images and their applications, in particular for television or video applications, and printing applications. Integrated-optical structures are used on a mount, in particular a substrate. An image is generated by deflecting color light beams generated into a viewing space, which deflection is effected in synchronism with color setting and intensity- or amplitude modulation of the light. All electronic and optical assemblies for color image generation may be integrated on a mount either monolithically or in hybrid fashion. The color generation system may be implemented as an encased module. |

DETAILED DESCRIPTION The primary object of the invention is to solve the problem of creating comparably small and simply constructed, as well as universally usable, color image generation systems for generating real or virtual images, which color image generation systems feature improved characteristics, such as a higher image resolution or a more comprehensive color spectrum, and thus enable new applications in basically known systems. The arrangement is intended to generate, and write into space, an intensity- or amplitude-modulated as well as color-modulated color signal, in particular for the generation of a two-dimensional or three-dimensional television or video image, or a printed image. The purpose of the invention is, in the most extreme embodiment of the invention, to integrate all electronic and optical components of a color image generation system on one mount and to provide this as a module with electrical connections and an optical output. The object of the invention is achieved in a color image generation system comprising at least one light source for emitting light of at least one wavelength or one wavelength range, at least one optical waveguide responsive to said light emitted by the light source, at least one controllable modulation device, means for beam shaping and beam deflection and one control unit coupled to the at least one controllable modulation device for controlling at least one of intensity- or amplitude modulation and color modulation of the light as well as to the means for beam shaping and beam deflection. The means for beam shaping and beam deflection by which the at least one of intensity- or amplitude modulated and color modulated light is adapted to being deflected in at least one spatial direction using the control unit in synchronism with modulation control, and an image field are adapted to being written to in digital fashion (light points) or in analog fashion (light beam). Between the at least one light source and the means for beam shaping and beam deflection, a mount is arranged on which at least one optical waveguide is mounted such that a minimum of one optical waveguide capable of transmitting efficiently the wavelengths or wavelength ranges according to a predetermined application injects intensity- or amplitude modulated and/or color modulated light into the means for beam shaping and beam deflection
