Feature Of The Week 3/18/12: Research Results from Shanghai Jiaotong University on Optical Coherence Tomography for Whole Eye Segment Imaging
Researchers from Shanghai Jiao Tong University, Shanghai Institute of Technology, Peking University, and UCLA recently published a paper on “Optical coherence tomography for whole eye segment imaging". Below is a summary of their work.
We proposed a dual focus dual channel spectral domain optical coherence tomography (SD-OCT) for simultaneous imaging of the whole eye segments from cornea to the retina. By using dual channels the system solved the problem of limited imaging depth of SD-OCT. By using dual focus the system solved the problem of simultaneous light focusing on the anterior segment of the eye and the retina. Dual focusing was achieved by adjusting the collimating lenses so the divergence of the two probing beams was tuned to make them focused at different depth in the eye. We further achieved full range complex (FRC) SD-OCT in one channel to increase the depth range for anterior segment imaging. The system was successfully tested by imaging a human eye in vivo.
