Abstract

A novel medical imaging method has been created with theoretical demonstration for its feasibility. The method uses multi-beam interference to create destructive interference in the propagation path to reduce composite light intensity and so reduce light absorption and scattering, and to create constructive interference at a designed position to produce composite light intensity maximum which forms an internal light layer to illuminate the target tissue. This method can enhance signal strength more than 600dB. The imaging depth can be over 5cm in human body. The imaging resolutions are less than1μm along object plane and near1μm along direction of depth of field.
