Способ оптической томографии относится к оптическому приборостроению и, в частности к методам дефектоскопии оптических материалов по таким показателям, как пузырность и безсвильность. Изобретение обеспечивает получение объективных результатов измерения с повышенной точностью и достоверностью, построение томограммы величины и распределения дефектов (пузырей и свилей) по объему материала. Для этого устраняют влияние пограничной поверхности материала, зондируют материал оптическим излучением встречными пучками с одинаковыми апертурными углами, перемещают точки схождения встречных пучков по объему материала, регистрируют приемной системой проходящее, рассеянное и отраженное от дефектов в материале излучение, проводят корреляционную обработку части зондирующего излучения, не проходящего в материал, совместно с проходящим, рассеянным и отраженным от пузырей и свилей в материале излучением, регистрируют положение точки схождения встречных зондирующих пучков.The method of optical tomography relates to optical instrumentation and, in particular, to the methods of flaw detection of optical materials in such indicators as bubbling and weakness. The invention provides obtaining objective measurement results with increased accuracy and reliability, construction of a tomogram of the magnitude and distribution of defects (bubbles and swells) by the volume of the material. To do this, eliminate the influence of the boundary surface of the material, probe the material with optical radiation by opposing beams with the same aperture angles, move the convergence points of the opposing beams throughout the material, record the transmitted, scattered and reflected radiation from defects in the material passing into the material, together with the passing, scattered and reflected from the bubbles and swells in the material radiation, register the position of the point convergence of oncoming probing beams.
