Recent innovations in computational and electronic technologies have drastically enhanced the three-dimensional (3-D) optical metrology field in terms of measuring speed and accuracy, as well as expanded applications. High-speed 3-D optical metrology is a platform technology that could benefit numerous scientific studies and engineering concerns including but not limited to manufacturing, medical sciences, robotics, etc.

Lately, a number of novel high-speed 3-D optical metrology methods have been developed, and these technologies have been applied to fields ranging from medicine, computer science, robotics, biometrics, homeland security, agriculture, and biology, to automotive, manufacturing, and entertainment industries. For example, Microsoft Kinect has penetrated 3-D optical metrology into our daily lives; real-time 3-D metrology techniques have permitted in situ inspection in the electronics industry; and high-speed 3-D sensing devices have enabled better robotic navigation.

This special section assembles a good number of high-speed 3-D optical metrology technologies, as well as a few representative applications. Active high-speed 3-D shape measurement based on fringe projection requires generating and projecting fringe patterns rapidly. T. Bell and S. Zhang summarize their contributions using the digital light processing (DLP) platforms; C. Casey et al. discuss the modified composite pattern illumination method; S. Heist et al. present their recent innovation of using an LED matrix; L. Lu et al. use triangular patterns for high-speed 3-D shape measurements; M. Schaffer et al. summarize their work using statistical patterns; and T. Wakayama and T. Yoshizawa present yet another rapid fringe pattern generation using spatiotemporal modulated laser light.

High-speed 3-D optical metrology not only requires high-speed pattern generation, but also high processing speeds and better system design. Parallel computing is apparently one of the preferred methods. C. Brauer-Burchardt et al. discuss the method of using geometric constraints to reduce the required number of patterns for 3-D shape reconstruction and thus improve measurement speeds, and K. Zhong et al.’s paper discusses the parallel architecture for high-speed measurements.

There are various ways of improving the measurement accuracy. One obvious method is to improve calibration, which was discussed in Y. Zhang’s paper. Q. Xue et al. presented the idea of improving the center detection method for accuracy improvement; V. Marin et al. discuss an interesting but important aspect to increase the accuracy of triangulation through system design optimization.

Data received from high-speed 3-D sensors can benefit numerous application areas. This special section includes some critical areas of applications. 3-D facial recognition in biometrics, for example, can be greatly benefited from high-quality 3-D data captured from 3-D sensors. W. Luo et al. present their facial recognition methods based on advanced mathematical tools: Ricci flow and mass transportation. N. Burns and J. Watson use in-line holograms to measure marine organisms, and D. Serrano-García et al. apply 3-D optical metrology for dynamic temperature fields measurements.

We appreciate the authors who submitted their novel methods or applications to this special section, as well as the tremendous support from SPIE.
