AB  - By using the principle of stereovision, 3D digital image correlation (3D-DIC) can 
      determine the 3D morphology and deformation of a target and has been widely used 
      in experimental mechanics as a noncontact 3D measurement technique. To eliminate 
      the limitations of the conventional 3D-DIC system, this study proposes a 
      calibration-free single-lens 3D-DIC system based on a bilateral telecentric lens 
      and a bi-prism. The performance of the proposed system is verified by tests of 
      rigid-body translation along the out-of-plane direction. As a comparison, the 
      same rigid-body translations are measured using a single-entocentric-lens 3D-DIC 
      system. The results show that the measurement accuracy of the proposed system is 
      higher than that of the entocentric-lens-based one. As an application, the 
      proposed system is used to measure the thermal linear expansion of a ceramic 
      plate at elevated temperatures. The reasonable measurement results verify its 
      applicability in deformation measurements, even in high-temperature environments.
