A scanning electron microscopic stereo-photography is a very useful method for the observation of micro objects in as far as their surfaces are not smooth and have many reference points. A new method for taking a pair of SEM stereo-photographs of any micro object was proposed. An emulsion of polymer latex was used by spraying it on to the object, where micro grains of polymer latex could be deposited separately and randomly. SEM photographs of those micro grains are considered as random patterns and applied to carriers of object surface profiles. And their stereo-photographs are similar to random carrier stereo-photographs. An auto-correlation of a random pattern can be easily obtained by many means. Therefore, optical techniques were used for measuring the fine surface profiles.
