Simultaneous en-face imaging of multiple layers with multiple reference optical coherence tomography
Neuhaus K, OGorman S, McNamara P, Alexandrov S, Hogan J, Wilson C, et al.
J Biomed Opt
. 2017 Aug;
22(8):1-7.
PMID: 28831794
A technique based on multiple reference optical coherence tomography (MR-OCT) is proposed for simultaneous imaging at multiple depths. The technique has been validated by imaging a reference sample and a...
