Full range, dual depth optical coherence tomography for ophthalmology

We present spectral-domain optical coherence tomography (SD-OCT) using a single spectrometer with dual illumination and interlaced detection at 830 nm, which can provide anterior segment and retinal tomograms simultaneously. For the full-range imaging, which is needed especially for the anterior segment imaging, we employed vestigial sideband (VSB) filter for the effective mirror artifact removal during the off-pivot, full-range approach in SD-OCT.
