Abstract
An apparatus and method are provided. In particular, a radiation can be provided which includes at least one first electro-magnetic radiation directed to a sample and at least one second electro-magnetic radiation directed to a reference, whereas a frequency of the radiation varies over time. An interference between at least one third radiation associated with the first radiation(s) and at least one fourth radiation associated with the second radiation(s) can be detected to generate an electrical first signal. A second signal associated with at least one phase of at least one frequency component of the electrical first signal can be obtained. Further, comparison data can be generated by comparing the second signal to at least one particular information.
