Shearography, one of the most up-to-date scientific and technological achievements, is a powerful measurement method capable of measuring micro-strains,stress distributions, strain distributions, etc. with high accuracy,and has been studied worldwide. Especially with the rapid development of computers and solid-state imaging sensors, shearography is becoming a more important tool in the measurement of microstrain. And shearography is widely used worldwide today due to its simplicity of optical systems, low measurement environmental requirements and the advantages of using inexpensive...
