We propose a fourth-order interference scheme for optical coherence tomography operating with broadband
incoherent (or quasi-incoherent) light. It is shown that using this proposal, an axial resolution improvement by
a factor of 2 and a better sensitivity for weakly reflecting samples are obtained than with the standard
second-order correlation scheme. From a practical perspective, we suggest the use of broadband Q-switched
pulses and performing ultrafast intensity correlation with a nonlinear crystal. The global performance of our
proposal is illustrated by means of numerical simulations [-]
