About

Akihiko Itoh is a pioneering figure in plasma diagnostics, renowned for developing advanced optical emission tomography techniques to map the three-dimensional structure of industrial plasmas. His research centers on the spatial characterization of inductively coupled plasma (ICP) reactors and magnetron discharges, with a focus on understanding the distribution of excited species and sputtered particles under non-equilibrium conditions. Itoh’s major contributions include the creation of robot-assisted optical systems that enable precise, automated tomographic imaging of plasma emission and absorption, allowing for the visualization of complex discharge structures. His most-cited work, "Three Dimensional Optical Emission Tomography of an Inductively Coupled Plasma" (1997), with 52 citations, demonstrates how pressure and power influence the net production rate of excited argon species. His 1996 paper on robot-assisted tomography (38 citations) further explores spatial profiles in ICPs, while his studies on dc magnetron discharges (17 citations) extend these methods to sputtering applications. By integrating industrial robotics with plasma diagnostics, Itoh has provided researchers with powerful tools to visualize and optimize plasma processes, making his work foundational for both fundamental plasma physics and applied semiconductor manufacturing.
