It has been proved that the OCT system behaves as a linear shiftinvariance system and can be described precisely by a coherent transfer function (CTF).
If the space shiftinvariance is replaced by the time shiftinvariance, the high resolution frequency estimation can be obtained using a single vector sensor.
