Speckle reduction in optical coherence tomography by path length encoded angular compounding
First Claim
1. An apparatus for obtaining information associated with a structure, comprising;
- an optical first arrangement including an optical section that is configured to provide a first radiation and a second radiation that are forwarded to the structure, wherein the first and second radiations have different path lengths;
an interferometer second arrangement configured to receive third and fourth radiations from the structure associated with the first and second radiations and a fifth radiation received from a reference; and
a computer third arrangement configured to generate the information of images associated with the structure which have different delays with respect to one another based on the third, fourth and fifth radiations.

Abstract
Accordingly, exemplary embodiments of an apparatus obtaining information associated with a structure can be provided. For example, with a first arrangement, it is possible to separate at least one first electro-magnetic radiation into a first radiation and a second radiation forwarded to the structure, with the first and second radiations having different path lengths. Using a second arrangement, it is possible to receive third and fourth radiations from the structure associated with the first and second radiations and a fifth radiation received from a reference. Further, with a third arrangement, it is possible to generate data corresponding to an amount of a ranging depth within the structure associated with the second arrangement. For example, a difference between the path lengths of the first and second radiations is equal or greater than the ranging depth.
