Cedric Blatter, Branislav Grajciar, and Christoph M. Eigenwillig et al. We present a Bessel beam illumination FDOCT setup with FDML buffered swept source at 1300nm. An extended focus is achieved due to the Bessel beam that preserves its lateral extend over a large depth range. Decoupling the illumination from the Gaussian detection improves the sensitivity as compared t ... [Proc. SPIE 8091, 809104 (2011)] published Thu Jun 09, 2011.
