Abstract

Optical coherence tomography (OCT) is a non-invasive imaging technique with many applications and widespread use in ophthalmology [1]. The axial resolution in OCT is inversely proportional to the bandwidth of the optical source used but the improved axial resolution comes at the price of more significant effects of dispersion stemming from the imaging system and the imaged medium. In recent years spectral intensity (SI) OCT has been shown as a classical realisation of quantum OCT to remove even orders of dispersion intrinsically [2,3]. One major drawback of SI OCT is however halving of the imaging range which is crucial in spectrometer based OCT which is limited by the spectral resolution and hence number of pixels of the spectrometer. In this work we demonstrate SI OCT with the full imaging range.
