Изобретение относитс к области оптичеciKoro неразрушающего ко трол материалов и изделий и может быть нслользоеано дл определени шероховатости поверхности или дл дефектоскопии изделий.The invention relates to the field of optical non-destructive materials and products, and can be used to determine surface roughness or for defectoscopy of products.
По авт. св. oNb 261708 известен способ измерени шероховатости поверхности издели , заключающийс в том, что на поверхность «йдели направл ют поток света под задалным углом падени , а отраженный Свет прпиимают фоторегистратором и но параметрам отраженного света суд т о контролнруемом объекте.By bus. St. oNb 261708 a method for measuring the surface roughness of an article is known, which means that the light is directed to a surface by a predetermined angle of incidence, and the reflected light is transmitted by the photo recorder and the object to be detected is reflected to the parameters of reflected light.
Одиа;ко при осуществлении этого способа происходит 1снижение точности с увеличением уровн освеи1ениости объекта.When this method is implemented, the accuracy decreases with an increase in the level of illumination of the object.
Целью изобретени -вл етс новышение точности.The aim of the invention is an increase in accuracy.
Дл этого падаюни1Й пучок лучей пропускают через пол ризатор, а перед фоторегистратором устанавливают другой пол ризатор .For this, the falling beam is transmitted through the polarizer, and another polarizer is installed in front of the photo recorder.

Предлагаемы способ по сн етс чертеЖО .М. Световой ното.к от источника / пол ризуетс первым пол ризатором 2, затем, отража сь от контролируемой поверхности 3, проходит через второй пол ризатор 4 и попадает iB фоторегистратор 5.The proposed method is illustrated in the drawing .M. The light note from the source / polarizes the first polarizer 2, then, reflecting from the test surface 3, passes through the second polarizer 4 and enters the iB photo recorder 5.
УТОл скрещивани пол ризаторов уста авливаетс в зависилшсти от ан 13отро;п11П контролируе1 ой иоверхности так, чтобы поток отраженного света от бездефектпой новерхност на выходе пол ризатора был мин1 мальным .The crossover polarization crossover is set to depend on the winding of the polarizer; the control surface is controlled so that the flow of reflected light from the defect-free surface at the polarizer output is minimal.
