An optical apparatus for creating an image of object features buried underneath color filters. The apparatus includes: an illumination light source producing an illuminating light, the illumination light source incorporating at least three laser light emitters operating at different wavelengths, the illuminating light being a combination of light signals produced by the at least three light emitters; an electronic control module coupled to each of the at least three laser light emitters and configured to drive each of the at least three laser light emitters using a pulsed driving signal with controllable amplitude and temporal pulse parameters; an illumination optical path delivering the illuminating light from the illumination light source to the object; an image sensor for creating the image of the object using light collected from the object; and an imaging optical path for delivering the light from the object to the image sensor. The three laser light emitters are operated in a saturation mode to reduce the illumination light coherence and eliminate the resulting speckle.
