PROCESS GENERATING IMAGES OF INTERNAL STRUCTURE OF OBJECTS Russian patent published in 2002 - IPC

FIELD: optical instrumentation, specifically, coherent tomography of scattering biological objects with high spatial resolution. SUBSTANCE: coherent radiation of wide spectrum is split into reference and object beams. Object beam is focused inside object and backward radiation scattered by object is selected from focusing region by method of confocal filtration. Frequency shift is entered into reference beam. Reference and scattered radiations are spatially combined and as result of their interference summary radiation including light beats is obtained. Summary radiation is subjected to spatial spectral analysis and light beats are detected in each independent element of spectral analysis. Two-dimensional scanning of focusing point along focusing plane is carried out and three-dimensional image of internal structure of object is obtained after mathematical processing. EFFECT: increased productivity of recording of images of internal structures of objects. 2 cl, 9 dwg
