Far-field holography of ampule contaminants.
Detection and measurement of contaminating particles in cylindrical ampules have been achieved using far-field holography. The degradation of the images caused by the cylindrical nature of the ampule was overcome by index matching and clear images of particles as small as 5 microm in diameter were obtained.
