Method and apparatus for three-dimensional spectrally encoded imaging
First Claim
1. A method for providing information associated with at least one portion of a sample, comprising:
- encoding at least two wavelengths of at least one particular electro-magnetic radiation provided on a sample, each of the at least two wavelengths being utilized to determine at least one respective transverse location of a plurality of transverse location of the at least one portion;
obtaining at least one relative phase between at least one first electro-magnetic radiation electro-magnetic radiation being returned from the sample and at least one second electro-magnetic radiation returned from a reference to determine at least one relative depth location of the at least one portion; and
providing the information of the at least one portion based on each of the transverse locations and the at least one relative depth location.

Abstract
A method and apparatus for providing information associated with at least one portion of a sample can be provided. For example, at least one wavelength of electro-magnetic radiation provided on a sample can be encoded to determine at least one transverse location of the portion. A relative phase between at least one first electro-magnetic radiation electro-magnetic radiation being returned from a sample and at least one second electro-magnetic radiation returned from a reference can be obtained to determine at least one relative depth location of the portion. Further, the information of the portion can be provided based on the transverse location and the relative depth location. For example, the information can be depth information and/or three-dimensional information associated with the portion of the sample.
