One trial is reported on producing deformed lines of an object scanned by a laser beam, that is socalled deformed grating patterns. Such properties inherent in a laser beam as being narrow in width and high in intensity can be effectively utilized for the purpose. With the aim of getting appropriate patterns, geometrical relations between a rotating mirror and an incident light are investigated, and a practical scanning apparatus is deviced and manufactured as a prototype. The photogrphic pattern of the object with deformed grating lines reveals Moire fringes showing contours mapping when super-imposed by 4 reference grating. Experimental applications with one pair of these patterns show that cross sections of the object can be drawn and that piling up these sections can reproduce the original shape of the subject body.
