dc.description.abstract |
The recent advent of ultra high frame rate cameras gives rise to the possibility of
constructing swept source full-field OCT systems with achievable volume rates approaching
10Hz and net A-scan rates approaching 10MHz. Unfortunately, when illuminated with
partially coherent light, full-field OCT in turbid media suffers resolution and SNR
degradation from coherent multiple scattering, a phenomenon commonly referred to as
crosstalk. As a result, most FFOCT systems employ thermal sources, which provide spatially
incoherent illumination to achieve crosstalk rejection. However, these thermal sources
preclude the use of swept source lasers. In this work, we demonstrate the use of a
carefully configured FFOCT system employing multimode fiber in the illumination arm
to reduce the spatial coherence of a partially coherent source. By reducing the coherence
area below the system resolution, the illumination becomes effectively spatially incoherent
and crosstalk is largely rejected. We compare FFOCT images of a USAF test chart positioned
beneath both transparent and turbid phantoms using both illumination schemes. © 2010
