Abstract

We present a novel approach for spectral domain optical coherence tomography (OCT) in this proposal. Our method incorporates a depth-multiplexing strategy by utilizing multiple reference arms, each centered at different depths within the eye. By simultaneously capturing and employing phase multiplexing during post-processing, we can effectively separate the interferograms from these arms. The primary advantage of our technique lies in its ability to measure the entire eye length in a single shot, all while ensuring a cost-effective system design.
