Abstract
In this work we demonstrate spectrometer based mid-infrared (MIR) optical coherence tomography (OCT) at 4 µm but with an increase of state-of-the-art imaging speed by at least 10 times. The improvement is based on exploiting a chirped periodically poled lithium niobate crystal. We show more than 3 kHz line rate OCT imaging. With this significant increase in imaging speed we hope to expand the efficacy of mid-infrared OCT.
