Abstract

Comparison of two illumination modes for wide-field optical coherence tomography has revealed that spatially coherent illumination generates coherent cross talk, causing significant image degradation, and that spatially incoherent illumination, with an adequate interferometer design, provides an efficient mechanism for suppression of coherent cross talk. This is shown by comparison of a pulsed laser with a thermal light source for a U.S. Air Force resolution target covered with a scattering solution made from microbeads as well as for an ex vivo tooth.

Schematic of a wide-field OCT setup with spatially coherent (flip mirror at 45°) and spatially incoherent (flip mirror vertical) illumination: Hg, mercury arc lamp; SF, single-mode fiber; MF, multimode fiber; IF, interference filters; RM, reference mirror; S, scanner; TS, translating stage; L1/2/3/5, achromatic lenses; L4, 10× microscope objective (NA, 0.25); PD, photodiode; A, amplifier. Inset, axial resolution measured in air for Hg (solid curve) and for MLTS (dashed curve) sources.

Cross-section wide-field OCT image of a U.S. Air Force resolution target covered with an 8-optical-depths scattering solution (g=0.92): (a) SCI, (b) SII, (c) cuts along the z axis of (a) (across the middle stripe), (d) cuts along the x axis of (b) (across the reflecting target interface). Curves labeled SII H2O are the same cuts of the same image acquired in water with SII. All curves are normalized and correspond to an average of 25 demodulated signals.
