Simultaneous en-face imaging of two layers in the human retina by low-coherence reflectometry

We show that with a fiberized multiple Michelson-interferometer-type configuration, transverse images from several layers in the human eye can be simultaneously obtained. We demonstrate the principle by producing simultaneous 100x100 pixel en-face images of a 4 mmx4 mm region on a postmortem retina for two depth positions 250 mum apart.
