“…They processed the gray fields of distinct channels, effectively separating thermal disturbance errors from measurement results. Notably, the experimental scope of this approach, as well as that in reference (Bao et al, 2019) was within the range of 180 8C-200 8C, and its effectiveness in eliminating thermal disturbance at higher temperatures remains unverified. In conclusion, numerous researchers have proposed methods to enhance the accuracy of DIC under hightemperature conditions.…”

“…Wu et al (2019) measured the mechanical properties of aluminum trioxide ceramics at 1,200 8C by using multilevel space sealing and regional isolation technology to minimize the space of the tested parts and reduce air flow when measuring the mechanical properties of external and internal surfaces at high temperature during the simulated flight process of aircraft. Bao et al (2019) utilized diffuse laser reflection to generate speckle patterns projected onto the test piece, capturing displacement field information in the presence of thermal disturbance. The authors subsequently employed corrections to alleviate the impact of thermal disturbance on the measured outcomes.…”

“…High temperatures will also result in haze effects from convection currents, which distort the image and introduce error to DIC measurements. Several countermeasures (Lyons 1996, Novak 2011, Leplay 2015, Su 2015, Ma 2019, Hao 2017, Bao 2019) will be investigated to improve the accuracy of high-temperature DIC against heat distortion.…”

Fish is a common and widely distributed creature. Its skin has a unique physiological structure and plays an important role in many fields. Fish skin also has important potential value for bionics research. This study aims to provide a method and a reliable data for the study of bionics. A method of measuring the mechanical properties of fish skin samples using a binocular stereo digital image correlation (DIC) system combined with a synchronous tensile testing machine was proposed. The mechanical properties (e.g., elastic modulus E and strain) of grass fish skin samples (GFSA) were tested in hydrophilic and dry states. A dual-frequency laser interferometer was used to calibrate the tensile testing machine synchronously, and the feasibility and strain accuracy of DIC in GFSA measurement were verified by finite element method (FEM). The results show differences in the mechanical properties of GFSA between different individuals, different parts, and different states. Under the same stress, the head was easy to deform, and the strain was the largest, and E was the smallest. The tail result was the opposite of the head result.
