FIELD: measurement technology, visualization of profiles of three-dimensional objects. SUBSTANCE: gear is meant to realize method of structurized illumination. It includes source of optical radiation, lighted sign coming in the form of spatial modulator of intensity of optical radiation, additional objective, objective, photographic recorder and digital electron unit. Digital electron unit has additional output to control spatial modulators of intensity of optical radiation connected to control input of modulator of intensity of optical radiation capable of control over spatial modulation of intensity of optical radiation. Structurized illumination of object is formed as aperiodic system of stripes. That is why each stripe distorted by relief of surface of tested object is identified unambiguously. EFFECT: raised accuracy and authenticity of test of linear dimensions of objects. 5 dwg
