In manufacturing production lines, it is essential to detect defects on the surfaces and coatings of all products to maintain quality and reliability. However, the reality is that existing measurement devices are not practical due to reasons such as slow inspection speeds or vulnerability to vibration environments. To overcome these challenges, our laboratory is conducting research and development on a device that enables non-contact and non-destructive three-dimensional shape measurement at high speed using light. For example, when scanning a space by projecting a two-dimensional tomographic image onto a two-dimensional camera in real time, completing the imaging in microseconds (one millionth of a second) allows for the clear capture of fine surface shapes of objects that are moving or vibrating quickly without blurring. This is called single-shot three-dimensional depth cross-sectional imaging and can be applied to inline total inspection. Furthermore, by advancing this technology, spectral information can be obtained for each position, structure, and layer. In other words, it is also possible to perform composition and material analysis for each structure that makes up the object.
