Micro-spectrometry in the visible range with full-field optical coherence tomography for single absorbing layers

Résumé

A time-domain full-field OCT adapted to the visible range and with an original configuration using an interferometric objective, that minimizes mechanical vibrations and some settings and that performs imaging without moving the sample, is presented. This setup achieves micrometer scale imaging, 1.5 μm in the axial direction and 1.2 μm in the lateral one. The principle of micro-spectrometry from OCT data by Fourier transform is described and the influence of some key data processing parameters is simulated and discussed. The experimental spectra reconstruction from tomographic data is validated by comparison with transmittance spectra. Imaging and spectra of dyes at a micrometer scale are obtained from the same data volume.
