AB  - An optimized 3D digital image correlation (3D-DIC) system using active optical 
      imaging is developed for accurate shape and 3D deformation measurements in 
      nonlaboratory conditions or extreme high-temperature environments. In contrast to 
      a conventional 3D-DIC system using white or natural light illumination, the 
      proposed active imaging 3D-DIC system is based on a combination of monochromatic 
      lighting and bandpass filter imaging. Because the bandpass filter attached before 
      the imaging lenses allows only the actively illuminated monochromatic light to 
      pass through and blocks all light outside of its bandpass range, the active 
      imaging 3D-DIC system is therefore insensitive to serious variations in ambient 
      light in nonlaboratory environments and to the thermal radiation of hot objects 
      in extreme high-temperature environments. Two challenging experiments that cannot 
      be performed by a conventional 3D-DIC system were carried out to verify the 
      robustness and accuracy of the developed active imaging 3D-DIC system. Because a 
      much wider application range can be achieved with relatively simple and 
      easy-to-implement improvements, the proposed active imaging 3D-DIC system is 
      highly recommended for practical use instead of the conventional 3D-DIC system.
