| Descripción |
The focus of this paper is a comparison of the strain-measuring
characteristics of one type of commercially available fiber-optic strain
sensor with the performance of conventional resistance strain gages.
Fabry-Perot type fiber-optic strain sensors were selected for this testing
program. Comparative testing is emphasized and includes load testing
at room temperature with apparent strain characterization cryogenically
and at elevated temperatures. The absolute accuracy of either of these
types of strain gages is not addressed.
Introduction
Langley Research Center (LaRC) uses strain gages in many varied and challenging test environments.
As testing scenarios become more demanding, not only at Langley but at other testing centers, there is the
realization that current strain gage technology does not and cannot provide a reasonable means for
measuring strain when certain testing requirements are encountered. A relatively new type of strain
sensor, the "fiber-optic" (F-O) strain g...
