In-situ large area optical strain measurement using an encoded dot pattern |
摘要 |
A method of measuring strain in a test specimen comprises the steps of placing a pattern of marks on a surface of the test specimen, wherein the pattern of marks includes a plurality of target marks and a plurality of sets of coded marks, using the sets of coded marks to identify locations of at least two of the target marks, and using a change in distance between at least two of the marks to determine strain in the test specimen. An apparatus that performs the method is also provided.
