First Claim
Patent Images
1. A system to compensate for a dispersion in at least one portion of an image, comprising:
- a processing arrangement configured to obtain information associated with the at least one portion of the image, the at least one portion of the image being associated with the interference signal that includes a first electro-magnetic radiation received from a sample and a second electro-magnetic radiation received from a reference, wherein the processing arrangement is configured to determine (i) complex spectral data that is based the interference signal, and (ii) a phase of at least one spectral component of the complex spectral data, and wherein the processing arrangement is further configured to compensate for the dispersion in the at least one portion by controlling the phase of the at least one spectral component of the complex spectral data.

Abstract
A system, process and software arrangement are provided to compensate for a dispersion in at least one portion of an image. In particular, information associated with the portion of the image is obtained. The portion of the image can be associated with an interference signal that includes a first electromagnetic radiation received from a sample and a second electromagnetic radiation received from a reference. The dispersion in the at least one portion of the image can be compensated by controlling a phase of at least one spectral component of the interference signal.
