Abstract:To address the challenge of obtaining key device strain
parameters within narrow spaces, this paper presents the design of a
small-sized optical imaging probe with an independent optical system
based on the basic principle of digital image correlation (DIC). To
validate the strain measurement accuracy of the probe, a
high-temperature heating system was built under in a laboratory
setting, and experimental tests involving room temperature strain
measurement and high temperature thermal expansion c… Show more
