Claims (8)
ΔZ = ΔY/(tgα-tgβ),
где ΔZ - истинное значение глубины дефекта;
ΔY - измеренная величина искривления кольцевого изображения в поперечной плоскости;
α - угол падения пучка лазерного излучения на поверхность трубы, определяемый как угол между осью пучка зондирующего лазерного излучения и нормалью к контролируемой поверхности трубы;
β - угол визирования, определяемый как угол между направлением визирования на контролируемую поверхность трубы и нормалью к этой поверхности.3. The method according to claim 1, characterized in that the judgment on the state of the surface is carried out in accordance with the mathematical expression
ΔZ = ΔY / (tgα-tgβ),
where ΔZ is the true value of the depth of the defect;
ΔY is the measured value of the curvature of the annular image in the transverse plane;
α is the angle of incidence of the laser beam on the pipe surface, defined as the angle between the axis of the probe laser beam and the normal to the controlled surface of the pipe;
β is the angle of sight, defined as the angle between the direction of sight to the controlled surface of the pipe and the normal to this surface.
