3-dimensional imaging is believed to be the next generation imaging technology, which will eventually replace the current plane image. In spite of the fact that the first stereoscopic viewing device was introduced on 1838, the lack of supporting technologies such as high resolution display devices, high speed electronics, high resolution viewing zone forming optics and high speed image processing deterred further development in 3-D imaging for a long time. However, the recent progress in high resolution and high density flat panel display devices as well as PC technology have enabled the construction of a number of multiview 3-D imaging systems. This one-day course is intended for those who have an interest in 3-D imaging. Recent progress in 3-D imaging technologies and their perspectives will be presented, the theoretical background behind various 3-D imaging systems will be covered in-depth and fundamental limits imposed on the 3-D imaging process will be explained.
