Paper Abstract

Due to the multiple scattering of light in biomedical tissue, the imaging depth of conventional optical coherence tomography is limited to 1-2 millimeters. In this research, a reflection-matrix-method-based optical coherence tomography has been developed to extend the imaging depth into scattering medium. After obtaining the matrix, singular value decomposition and imaging reconstruction are carried out in the post-process to recover the target image beneath turbid media. Specifically, in order to speed up the matrix measurement and reduce the phase noises during the acquisition process, wide-field heterodyne detection is adopted in our system by using a high-speed lock-in camera.
