CORRELATION OF CONCURRENT NON-INVASIVELY ACQUIRED SIGNALS

摘要

The invention provides a method and system for non-invasive analysis, especially suitable for determining attributes of targets, such as measurement of layer thickness of tissue, or the concentration of glucose within human tissue. The invention includes an optical source and an optical processing system that provides probe and reference radiation; applies the probe beam to the target to be analyzed; re-combines the probe and reference beams interferometrically, to generate one or more concurrent interferometric signals that are detected and processed. The location within the target to which an interference signal relate is aligned and registered with respect to the target is by means of a field of light based imaging device. The invention is not limited to human tissue in vivo, nor to in vivo non-invasive analysis.

主权项

1. A method of determining an attribute of a target, comprising:
generating probe radiation; applying at least a portion of said probe radiation to said target to generate back-scattered radiation; generating reference radiation; combining said back-scattered radiation and said reference radiation to produce at least one interference signal; detecting said interference signal by means of a detector; extracting concurrent information from said detected interference signal; acquiring a light field based image of the target using a light field imaging device; registering said concurrent information extracted from said detected interference signal with said light field based image; and outputting data.
