Method and system for creep measurement |
| 摘要 |
A method and system for monitoring creep in an object are provided. The creep monitoring system includes a creep sensor assembly that includes at least one image pattern pair disposed on a surface of the object. The creep monitoring method includes receiving information from the creep sensor assembly regarding an observed creep and an offset associated with the object, correcting the observed creep using the information regarding the offset and outputting the corrected information relative to the creep. |

1. A method of monitoring creep in an object, comprising:
monitoring a creep sensor assembly comprising an image pattern pair disposed on a surface of the object, wherein the image pattern pair comprises a first pattern and a second pattern; receiving information from the creep sensor assembly regarding an observed creep associated with the object; receiving information from the creep sensor assembly regarding an offset of the creep sensor assembly obtained from a comparison of relative change in frequency of the first and second patterns; correcting the observed creep using the information regarding the offset, and outputting the corrected information relative to creep. |
