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.

Apparatus for viewing through optical thin film color filters and their overlaps

System and method for selectively viewing features of objects, including features hidden under non-transparent materials. The system includes: illuminating light source producing illuminating light having controlled angular spectrum; homogenizing optics for spatial intensity modulation of illumination light; dephasing optics to reduce or suppress interference pattern in image due to the coherence of illumination light; infinity corrected objective directing the illuminating light on the object and collecting light from the object; illumination optical path delivering the illuminating light from the illuminating light source to infinity-corrected objective; relay optics for introducing necessary tilt angle for rays of the illuminating light entering the infinity corrected objective; adjustable iris vignetting free aperture of optical fiber; apodizing element within relay optics for spatial modulation of illumination intensity; image sensor for creating image of object; and imaging optical path for delivering light from object to image sensor, which includes tube lens, removable block and adjustable iris.
