Abstract

A power-efficient Fourier domain optical coherence tomography fiber system is presented free of mirror terms. The object and reference beams from the interferometer are spatially separated to illuminate different parts of the diffraction grating in the spectrometer according to a method inspired from the use of Talbot bands. In this way, the system is made sensitive to only one sign of the optical path difference in the interferometer.

Channeled spectrum visibility profiles for position 1, overlap of the object and reference beam (old method, squares); positions 2 and 3, when the reference beam is displaced on either side of the object beam by 2.74 โ€‰ mm (novel method, discs, position 2, and triangles, position 3). The curves resemble the profiles of visibility of the modified Michelson configuration with screens [7, 8].

Cross-section OCT images from the finger of a volunteer using the two beams superposed, position 1 of TS2 (left) and separated by 2.74 โ€‰ mm , position 2 of TS2 (right); depth range 2 โ€‰ mm in air in both images. In the left image, the OPD = 0 is placed inside the finger, while in the right image the finger is placed away from zero OPD, at a distance where the maximum visibility falls inside the finger (somewhere between the stratum corneum and epidermis).
