Способ бесконтактного контроля линейных размеров трехмерных объектов, заключающийся в многократном формировании на поверхности контролируемого объекта зондирующей структурированной подсветки путем освещения поверхности контролируемого объекта пучком оптического излучения, каждый раз с управлением пространственной модуляцией интенсивности пучка оптического излучения, последовательной регистрации изображений искаженной рельефом поверхности контролируемого объекта структуры зондирующей подсветки и определении высоты рельефа поверхности контролируемого объекта по степени искажения изображения структуры зондирующей подсветки, а двух других координат - по положению искажений структуры подсветки в зарегистрированных изображениях, отличающийся тем, что модуляцией пучка управляют так, что зависимость интенсивности освещения от номера кадра однозначно определяет точку на поверхности контролируемого объекта, а положение искажений структуры подсветки в зарегистрированных изображениях определяют по зависимости интенсивности в точке от номера изображения в зарегистрированной последовательности.A method of noncontact monitoring of the linear dimensions of three-dimensional objects, which consists in repeatedly generating a probing structured illumination on the surface of a controlled object by illuminating the surface of a controlled object with an optical beam, each time controlling the spatial modulation of the intensity of the optical radiation beam, sequentially recording images of the structure of the probing illumination distorted by the relief of the surface of the controlled object, and determining the height of the relief the surface of the controlled object according to the degree of distortion of the image of the structure of the probing backlight, and the other two coordinates according to the position of the distortions of the backlight structure in the recorded images, characterized in that the beam modulation is controlled so that the dependence of the light intensity on the frame number uniquely determines a point on the surface of the controlled object, and the position of the distortion of the backlight structure in the recorded images is determined by the dependence of the intensity at a point on the image number in registered sequence.
