| 摘要 |
The present invention concerns an optical system for the reproduction of color video images, comprising a source of illumination (1), an electro-optical modulator (3) formed from pixels associated with the colors red, green, and blue respectively, and optical collimation means (2) used to illuminate the entirety of the modulator. This system further comprises a series of wavelength-selective holographic lenses (6) making it possible to focus the light of each red, green, or blue component on the associated pixels of the modulator. Applications to videoprojectors and direct viewing.
