ABSTRACT:
A method and apparatus for cleaning, detecting, and/or removing contamination from the surfaces of nominally transparent materials utilizing internal illumination of those surfaces with at least one electromagnetic radiation beam at an angle of incidence equal to or greater than the critical angle for total internal reflection. With appropriate selection of light sources and materials, the technique is effective at detecting and removing water, ice, particles, films and a variety of contaminants.
