Three-dimensional stereoscopic imaging modality based on a single optical channel and detector

A three-dimensional stereoscopic imaging modality (3D-SIM) based on a single optical channel and detector was developed to overcome some of the limitations of conventional 3D-SIM. It produces 3-D stereoscopic images by adjusting the angle of a transparent rotating deflector (TRD) to generate disparity between left and right images. The angular effect of the TRD was demonstrated to investigate the feasibility of the proposed method in 3-D stereoscopic image generation. Results indicate that image disparity increased as a function of the rotation angles of the TRD, while maintaining adequate 3-D perception. These results are expected to facilitate the practical use of a 3D-SIM in medicine.
