Abstract
Official abstract text for this publication.
Methods and systems are provided for using optical interferometry in the context of material modification processes such as surgical laser or welding applications. An imaging optical source that produces imaging light. A feedback controller controls at least one processing parameter of the material modification process based on an interferometry output generated using the imaging light. A method of processing interferograms is provided based on homodyne filtering. A method of generating a record of a material modification process using an interferometry output is provided.
First claim
Opening claim text (preview).
We claim: 1. An inline coherent imaging system comprising: an imaging light source; at least one sample arm coupled to the imaging light source and configured to direct the imaging light to a sample location; a first reference arm coupled to the imaging light source and the at least one sample arm and having a first optical path length; at least one additional reference arm coupled to the imaging light source and the at least one sample arm and configured to have an optical…
