Claim:
1. An optical apparatus for creating an image of an object buried underneath one or more color filters, the apparatus comprising: a. an illumination light source producing an illuminating light, the illumination light source comprising at least three laser light emitters, each of the at least three laser light emitters operating at a different wavelength from the other light laser emitters, the illuminating light being a combination of light signals produced by the at least three light emitters; b. 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 applied to the each of the at least three laser light emitters; c. an illumination optical path delivering the illuminating light from the illumination light source to the object buried underneath one or more color filters; and d. an image sensor for creating the image of the object buried underneath one or more color filters using light collected from the object, wherein the pulsed driving signal applied to the each of the at least three laser light emitters exceeds a predetermined threshold corresponding to spectral broadening of the illuminating light.
