Abstract
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.
