Resumo

To detect and quantitatively evaluate the heterogeneity of an optically transparent object, a visualization method on the basis of the spectral-domain optical coherence tomography scheme was developed. In contrast to the classical technique, in the proposed method, an object is analyzed in transmitted light. Another specific feature of this method is the recording of spectral images using an acousto-optical filter, which is placed in the output channel of the interferometer. A prototype of a setup that implements this method is described. The results of measuring inhomogeneities of test objects are presented.
