Paper Abstract

This work reports a Linnik type single shot full-field optical coherence tomography (SS-FF-OCT), which uses a fast generalized analytic signal based complex Riesz transform scheme to reconstruct wide area en-face OCT images. The OCT interferometer is illuminated using a single broad band white light emitting diode (WLED) (wavelength range 470- 850nm, central wavelength 650nm) and detection unit is a two-dimensional (2D) charge complementary metal oxide semiconductor (CMOS) camera. The measured axial and lateral resolution (using 4x, NA=0.1 microscope objective) of the present system is 0.9μm and 3.9μm, very close to theoretical values. The measured imaging area using CMOS camera is 2150 x 2150μm2. The feasibility of the system is demonstrated by imaging scattering samples such as onion bulk and plant leaf. The present SS-FF-OCT is compact, fast (Riesz transform based scheme), stable, cost-effective, and provides comparable axial resolution.
