FIELD: construction.
SUBSTANCE: method of design of three-dimensional profiles of the object, including generation of sounding pulses of laser radiation for step scanning of the object in the plane transverse to the direction of the radiator movement, with consecutive processing of the reflected from the object signal to design profiles of objects, differs from the other methods by the fact, that before reflected signal gets processed a laser beam is generated in a discontinuous mode, generated beam is broadened, transformed into light beam of annular cross-section; generation of sounding pulses of laser radiation for step scanning of the object is conducted by successive alternative fragments cutting out from the cross-section of the received light beam of annular cross-section.
EFFECT: improving accuracy of measurement and article technological efficiency.
