    Variable lateral size imaging of the human retina in vivo by combined confocal/ en face optical coherence tomography with closed loop OPDlocked low coherence interferometry based active axial eye motion tracking
    We reported recently an active tracking device based on white light coherence ranging using a spectrally interrogated Michelson interferometer, which was used to monitor and correct for the axial displacement of the eye and head of the imaged subject in a confocal scanning ophthalmoscope/ en face OCT system (SLO/OCT) by tracking the axial position of the eye fundus. Both the tracking and imaging interferometers share the eye interface optics and the patient eye and also an optical path difference (OPD) changing device in the reference (fast voice coil mounted retroreflector), that keeps them locked at constant OPD values. As ...
