Full-field optical coherence microscopy based on acousto-optic filtration of interference images

The problem of three-dimensional near-surface imaging of microscopic structures is discussed. Anew scheme of optical coherence microscope with detection in the spectral domain is proposed. It is based on a broadband light source and filtration of interference images by a tunable acousto-optic imaging filter placed in the detection channel. The applicability of the scheme for analyzing depth distributions of object properties is experimentally demonstrated.
