Process, system and software arrangement for determining at least one location in a sample using an optical coherence tomography
First Claim
1. A system to determine at least one position of at least one portion of a sample, comprising:
- a computer input arrangement which obtains information 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; and
a computer processing arrangement which;
I. obtains at least one of depth information of the at least one portion of the sample based on multiple points within a single A-line of the first electro-magnetic radiation,II. applies at least one weight function to the depth information so as to generate resulting information,III. ascertains a particular information which is at least one of a surface position or a depth position of the at least one portion of the sample based on the resulting information,IIIA. modifies a range of the reference based on the particular information, andIV. generates an image of the at least one portion of the sample based on the obtained depth information of the at least one portion of the sample, and wherein the modification of the range of the reference is performed during the generation of the image.

Abstract
A system, process and software arrangement are provided to determine at least one position of at least one portion of a sample. In particular, information associated with the portion of the sample is obtained. Such portion may be 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. In addition, depth information and/or lateral information of the portion of the sample, may be obtained. At least one weight function can be applied to the depth information and/or the lateral information so as to generate resulting information. Further, a surface position, a lateral position and/or a depth position of the portion of the sample may be ascertained based on the resulting information.
