Optical coherence tomography imaging device and method

Abstract

The invention relates to an optical coherence tomography imaging device (100) for imaging a sample (1) comprising: - a light source (20) for emitting an incident light beam, - a scanning module (30) comprising an acousto-optic tunable filter (31) configured to spectrally diffract the incident light beam and select a wavelength of the incident light beam, the scanning module (30) providing a diffracted light beam at the selected wavelength, the acousto-optic tunable filter being driven by a modulable electrical control signal; - a multimode optical fiber (60) arranged to adjust a spatial coherence of the diffracted light beam; - an optical coherence tomography module (90) forming an interference light beam;- an imaging detector (120) configured to record the interference light beams and to form, from the interference light beams, an image of the sample.
