FIELD: measuring equipment.
SUBSTANCE: method includes lighting object by collimated parallel beam of coherent monochromatic light, directed at angle of raising of screw surface relatively to object axis, as which object with screw surface is used, receiving optical image of its profile and following processing of received profile of image to perform further calculations of its parameters, while lighting of object is performed concurrently on two portions by collimated parallel beams of coherent monochromatic light, directed at raising angle of screw surface relatively to object axis, while these two beams are positioned symmetrically relatively to longitudinal axis of object and two images of said profile are received, mutual position of separate elements in which does not depend on presence of vibrations and shaking.
EFFECT: higher quality.
