Abstract:
1. A system to determine at least one position of at least one portion of a sample, comprising: a computer processing arrangement which obtains information associated with the at least one portion of the sample, the at least one portion being associated with an interference signal that includes a first electro-magnetic radiation received from the sample and a second electro-magnetic radiation received from a reference, wherein the computer processing arrangement further: I. obtains at least one of depth information or lateral information of the at least one portion of the sample, II. applies at least one weight function to the at least one of the depth information or the lateral information so as to generate resulting information, III. ascertains a particular information which is at least one of a surface position, a lateral position or a depth position of the at least one portion of the sample based on the resulting information, and IIIA. modifies a length of the reference based on the particular information.
