Zusammenfassung: | A multicolored optical assembly (10) for providing a highlighter light beam (40) of steered light to a first intermediate target image (62), comprising a baseline optical path (14) generating a baseline light beam (42), the multicolored optical assembly (10) having a highlighter optical path (12) providing the highlighter light beam (40) of steered light, the multicolored optical assembly (10) being configured to combine the highlighter light beam (40) of steered light with the baseline light beam (42) to form a combined beam. The highlighter optical path (12) comprises a multicolored laser source (1, 3, 5) providing light to an integrator per color (2, 4, 6), the integrator per color providing a homogenized and collimated beam per color, a spatial phase modulator per color (2-7, 4-7, 6-7), wherein the homogenized and collimated beam per colour is incident upon the spatial phase modulator per color (2-7, 4-7, 6-7) and is phase modulated per color by the spatial phase modulator per colour (2-7, 4-7, 6-7), each spatial phase modulator having an active spatial phase modulator area, and means for converging steered light of the highlighter light beam (40) to be incident on the first intermediate target image (62). In a first case, an illuminated area of the converged steered light illumination incident on the first intermediate target image (62) is smaller than the active spatial phase modulator area. In a second case, the means for converging is configured for converging the homogenized and collimated beam per color onto the spatial phase modulator (2-7, 4-7, 6-7). For both cases, the converged steered light illumination is realized in such a way that a specular beam of unsteered light of the highlighter light beam (40) matches with a size of the first intermediate target image (62).
