    摘要: For displaying a color image by recombination of several single color images, parasitic noise like speckles due to scattering within the system, in particular when laser light is involved, with the invention a significant improvement with a low number of parts can be realized by use of a color wheel that comprises in radially divided zones refractive elements for redirecting light beams incoming at different impinging angles and redistributing elements, e.g. a hologram, that provide for a defined output beam in an optical axis. The sequence of the individual light processing zones on the color wheel are synchronized with respective laser sources. The invention combines the functionality of plural elements, reduces speckles and avoids losses.

    摘要: An image generation unit with an illumination unit for generating a plurality of coherent sub-beams and for illuminating an image modulator, including a light source, and a projection lens for superimposing each of the coherent sub-beams onto a projection screen plane. An optical set-up introduces angles between each two of the sub-beams, which are chosen to produce uncorrelated speckle patterns in the projection screen plane, resulting in an interference speckle pattern. A phase modulator including a liquid crystal cell changes its directory profile in a lateral manner, thereby being able to change the phase of light of each sub-beam individually.

    摘要: The present invention relates to an image generating apparatus (1) which comprises an illumination unit (20) having an intermediate face (21, S), as well as an image modulator (30) for generating an image (I). In addition a deflecting means (10) for deflecting a received light beam (L) of primary illumination light (L1) to said illumination unit (20) is provided in order to irradiate said intermediate face (21, S). Said deflecting means (10) is adapted to have—during the process of irradiating said intermediate face (21, S)—said light beam (L) subsequently in time irradiate different portions of said intermediate face (21, S) in order to thereby reduce the speckle effect.
