Toru IWANE studied theoretical physics especially astrophysics in Kyoto university and receive B.E. and M.E from Kyoto university. After then, he joined Nikon Corporation and started optical studying and designing. He developed and researched optical system ophthalmic instruments at first, and then automatic focus sensing system for a camera and see-through displaying system. From research of focus sensing system for camera, an idea of light field occurred to him. Now he is investigating in light field optics and computational photography. His main interest is reconstruction of 3D image in space as you see in SF films.
