Acousto-optic Filtration of Interfering Light Beams for Visualization of Amplitude and Phase Structure of Small-size Objects

AbstractA technique for acousto-optic image filtration in full-field interferometry is proposed. It is based on the spectral selection of light in the registration channel of the Michelson interferometer by an imaging acousto-optical tunable filter. The technique is applicable for various full-field spectral-domain systems in profilometry and optical coherence tomography. It is experimentally shown that registered spectral signals may be used for 3-dimensional visualization of structure of optically inhomogeneous objects
