Method and apparatus for performing optical imaging using frequency-domain interferometry

摘要

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.

1. An apparatus, comprising:
at least one first arrangement including a light source that is configured to provide a radiation 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, wherein the light source causes a frequency of the radiation provided by the at least one first arrangement to vary over time; at least one second arrangement including a detector that is configured to detect an interference between at least one third radiation associated with the at least one first radiation and at least one fourth radiation associated with the at least one second radiation to generate an electrical first signal, wherein the at least one second arrangement is configured to obtain a second signal associated with at least one phase of at least one frequency component of the electrical first signal; and a computer which generates comparison data by comparing the second signal to at least one particular information.
